Amakhemikhali Ezolimo Ama-hormone e-Auxin I-Sodium Naphthoacetate Acid I-Naa-Na 98% Tc

Izakhiwo zomzimba nezamakhemikhali

Lo mkhiqizo uyi-granule emhlophe, i-powder noma i-crystalline powder; Awunaphunga noma unephunga elincane, umnandi kancane futhi unosawoti. Lo mkhiqizo uncibilika kalula emanzini futhi uncibilika kancane ku-ethanol.

Izinzile emoyeni. Isixazululo sizinzile ku-pH engu-7-10. Sincibilika kakhulu emanzini (53.0g/100ml, 25℃). Sincibilika ku-ethanol (1.4g/100ml). Inani le-pH lesisombululo samanzi lingu-8. Amandla okuvimbela ukubila kanye namandla okubulala amagciwane abuthakathaka kune-benzoic acid. Ku-pH 3.5, isixazululo esingu-0.05% sivimbela ngokuphelele ukukhula kwemvubelo, kanti ku-pH 6.5, kudingeka ukuhlushwa kwesisombululo esingaphezu kuka-2.5%.

Izinzuzo kanye nokungalungi

(1) Ukuncibilika Okuhle Kakhulu: i-α-naphthalene acetate sodium emsulwa kakhulu inamanzi namafutha okuncibilika okubili, ngakho-ke ingenziwa ngokuzimela ibe amanzi, impuphu, ukhilimu, i-granule nezinye izinhlobo zomthamo, okulula kakhulu ukuyisebenzisa futhi inomphumela omuhle kakhulu. Ngenxa yokuthi iyi-molecule eyodwa esixazululweni, ihlakazeke ngokulinganayo, kulula ukuyimunca izitshalo, futhi okuqukethwe okuvamile kwe-80% ye-α-naphthalene acetate sodium kudinga ukuncibilikiswa nge-ethanol, ukusetshenziswa kwayo akulungile neze. Ikhona esimweni samaqembu ama-molecule ku-powder kakhilimu, ukuhlakazeka kwayo kubi, futhi umphumela awumuhle ngokwemvelo.

(2) Ubumsulwa obuphezulu, akukho ukungcola, imiphumela emibi engenabo ubuthi: ubumsulwa obuphezulu be-α-naphthalene acetate sodium ubumsulwa obungaphezu kuka-98%, buqukethe inani elincane lamanzi, abuqukethe okunye ukungcola okungokwemvelo, ngakho-ke ekusebenziseni kwayo ngempumelelo ububanzi bokuhlushwa ngokuvamile ngeke kubangele umonakalo wezidakamizwa ezitshalweni, kanye ne-α-naphthalene acetate sodium evamile ngenxa yokuqukethe ukungcola okungokwemvelo okungu-20%, Kububanzi bokusetshenziswa okusebenzayo kokugxila, kuzobangela umonakalo wezidakamizwa emaqabunga amancane, amahlumela kanye nezithombo zezitshalo. Ukukhanya kubangela amabala amnyama, okunzima kubangela ukufa, futhi kukhona ukungcola okungokwemvelo okubangela umonakalo emzimbeni womuntu kanye nemvelo. Noma yiluphi uhlobo lomlawuli wokukhula kwezitshalo kanye ne-pesticide, ubumsulwa bayo buhlobene nomphumela wayo, njenge-sodium α-naphthalene acetate 5ppm(5μg/g) enomthelela omuhle, kuyilapho i-sodium α-naphthalene acetate evamile idinga ukufinyelela ku-20ppm(20μg/g) ukuze ibe nomphumela.

(3) Ukuxubana okuhle: ubumsulwa obukhulu i-α-naphthalene acetate sodium ingasetshenziswa ngokuhlanganiswa nezindlela eziningi zokulawula ukukhula kwezitshalo, njenge: i-auxin, i-sodium nitrophenolate, izinto ezisusa izimpande, ama-fungicides, umanyolo, njll.; I-sodium alpha-naphthalene acetate evamile ngokuvamile ayisetshenziswa ngokuhlanganiswa.

Izici zokusebenza

I-α-naphthalene acetate sodium emsulwa kakhulu iyi-hormone yokukhulaumlawuli wokukhula kwezitshalongemiphumela emithathu emikhulu. Eyokuqala ukukhuthaza ukwakheka kwezimpande ezikhulayo kanye nokwakheka kwezimpande, ngakho-ke ingasetshenziswa ukukhuthaza izimpande zembewu kanye nokukhula kwezimpande, kodwa ukugxilisa kakhulu kungavimbela nokukhula kwezimpande. Eyesibili ukukhuthaza ukwanda kwezithelo kanye nezimpande zezimpande, ngakho-ke ingasetshenziswa njengento yokukhulisa, futhi ukuhlolwa kwensimu kuye kwafakazela ukuthi ingakhulisa kakhulu isivuno futhi ithuthukise ikhwalithi yamapentshisi enkawu, amagilebhisi, ikhabe, ukhukhamba, utamatisi, upelepele, isitshalo seqanda, amapheya, ama-apula. Ngesikhathi esifanayo, ikhuthaza ukwanda okusheshayo kwamaseli, futhi izinga lokukhula kwe-solanum elashwe liveza izinguquko ezimangalisayo. Umphumela wamakhowe ubaluleke kakhulu futhi awunciphisi ikhwalithi yesithelo. Eyesithathu ukuvimbela izimbali nezithelo eziwayo, ngomsebenzi wokulwa nokuwa. Ngaphezu kwalokho, inemisebenzi ye-auxin ejwayelekile, njengokukhuthaza ukukhula, ukukhuthaza ukwakheka kwe-chlorophyll, kanye nokukhuthaza ukuhlukaniswa kwamahlumela nezimbali. Ngakho-ke, inomphumela wokukhuthaza ukuqhakaza nezithelo, ukukhuthaza amagatsha namaqabunga aluhlaza, ukwandisa isivuno nokuthuthukisa ikhwalithi, kanye nokuthuthukisa ukumelana kwezitshalo nesomiso, ukubanda kanye nokufakwa.

Indlela yokusebenzisa

Indlela yokusebenzisa i-α-naphthalene acetate sodium emsulwa kakhulu

(1) Sebenzisa wedwa

I-sodium α-naphthalene acetate emsulwa kakhulu ingalungiswa ngokwehlukana ibe ngamanzi, ukhilimu, impuphu kanye nezinye izinhlobo zomthamo wokukhuthaza ukukhula, izimpande, ukulondolozwa kwezimbali, ukulondolozwa kwezithelo njalo njalo. Isilinganiso sokusetshenziswa kanye: amagremu ama-2 kuya kumakhilogremu angama-30 amanzi. Isikhumbuzo esikhethekile: inani elikhulu livame ukulimala ngemithi.

(2) Kusetshenziswa kanye ne-sodium nitrophenolate

I-sodium ye-α-naphthalene acetate emsulwa kakhulu ingahlanganiswa ne-sodium nitrophenolate, i-growth hormone, i-fungicide, umanyolo, njll. I-sodium ye-α-naphthalene acetate emsulwa kakhulu ingahlanganiswa ne-sodium nitrophenolate eJapan, iTaiwan inomlando weminyaka engaphezu kwengu-20, lezi zingxenye ezimbili zingasebenzisana ngokubambisana, zandise ukusebenza kahle kwe-spectrum yemithi, zisebenzise ukunciphisa ukuhlushwa, zombili zinomphumela we-sodium nitrophenolate, kodwa futhi zinomphumela we-sodium α-naphthalene acetate, ukuze kufezwe kabili umphumela ngesigamu somzamo.

Isicelo

Indlela yesenzo

I-sodium naphthalene acetate emsulwa kakhulu iyi-auxin plant regulator, engena emzimbeni wesitshalo ngamaqabunga, isikhumba esithambile kanye nembewu yezitshalo, futhi ithuthelwe ezingxenyeni zokukhula okunamandla (amaphuzu okukhula, izitho ezincane, izimbali noma izithelo) ngokugeleza kwezakhamzimba. I-sodium naphthalene acetate ngokusobala yakhuthaza ukuthuthukiswa kwesihloko sempande (impuphu yempande). Ingadala ukuqhakaza, ivimbele ukuwa kwezithelo, yakhe izithelo ezingenambewu, ikhuthaze ukuvuthwa kwasekuqaleni futhi yandise isivuno. Okwamanje, i-sodium naphthalene acetate ingathuthukisa nekhono lokumelana nesomiso, ukumelana nokubanda, ukumelana nezifo, ukumelana ne-saline-alkali kanye nokumelana nomoya oshisayo owomile wezitshalo. I-sodium naphthalene acetate emsulwa kakhulu yahlolwa eJapan, eTaiwan nakwezinye izindawo, futhi umphumela wokusetshenziswa kwayo wawungcono kakhulu kunowe-sodium naphthalene acetate ejwayelekile.

Indlela yokuhlonza

(1) Ngemva kokuthatha cishe u-0.5g walo mkhiqizo nokufaka u-10ml wamanzi ukuze uncibilike, isixazululo sibonise ukusabela okuhlukile phakathi kosawoti we-sodium ne-benzoate.

(2) I-spectrum yokumunca ukukhanya kwe-infrared yalo mkhiqizo kufanele ihambisane ne-spectrum yokulawula.

Ukuhlolwa kwenkomba

Uma uthatha i-1.0g yalo mkhiqizo, engeza u-20ml wamanzi ukuze uncibilike, engeza amaconsi amabili esisombululo se-phenolphthalein indicator; Uma sibonisa ubomvu obukhanyayo, engeza isixazululo se-sulfuric acid titration (0.05mol/L)0.25ml, ubomvu obukhanyayo kufanele bunyamalale; Uma kungenambala, engeza i-sodium hydroxide titrant (0.1mol/L)0.25ml, kufanele sibonise ubomvu obukhanyayo.

Thatha lo mkhiqizo, womise ku-105 ℃ kuze kube yisisindo esingaguquki, ukunciphisa isisindo akufanele kudlule u-1.5%.

Insimbi Enzima Thatha u-2.0g walo mkhiqizo, engeza u-45ml wamanzi, uvuselele njalo, engeza u-5ml we-hydrochloric acid encibilikisiwe, hlunga, uhlukanise u-25ml we-filtrate, hlola ngokomthetho, okuqukethwe kwensimbi esindayo akumele kudlule izingxenye eziyi-10 ngesigidi.

Thatha i-1g ye-sodium carbonate engenamanzi ukuze uthole usawoti we-arsenic, uyisakaze phansi naseduze kwe-crucible, bese uthatha u-0.4g walo mkhiqizo, uwubeke ku-sodium carbonate engenamanzi, uwumanzise ngamanzi amancane, ngemva kokomisa, uwushise ngomlilo ophansi ukuze uwufake ku-carbon, bese uwushisa ku-500 ~ 600 ℃ ukuze uwushise ngokuphelele, uwupholise, engeza u-5ml we-hydrochloric acid kanye no-23ml wamanzi ukuze uwuncibilikise, kufanele uhlangabezane nezidingo ngokomthetho (0.0005%).

Ukunqunywa kokuqukethwe

Thatha cishe u-1.5g walo mkhiqizo, uwulinganise kahle, uwubeke endaweni yokuhlukanisa, engeza u-25ml wamanzi, u-50ml we-ether kanye namaconsi amabili e-methyl orange indicator liquid, u-titrate one-hydrochloric acid titrant (0.5mol/L), uxukuze ngamaconsi kuze kube yilapho ungqimba lwamanzi lubomvu ngokusawolintshi; Hlukanisa ungqimba lwamanzi bese ulubeka ebhodleleni elithambile eline-plug. Geza ungqimba lwe-ether ngamanzi angu-5ml, engeza u-20ml we-ether ebhodleleni eliyindilinga, qhubeka no-titration ngesisombululo se-hydrochloric acid titration (0.5mol/L), bese uxukuze ngamaconsi kuze kube yilapho ungqimba lwamanzi lubonisa umbala obomvu ngokusawolintshi. I-1ml ngayinye ye-hydrochloric acid titrant (0.5mol/L) ilingana no-72.06mg we-C7H5NaO2.
