Amakhemikhali Ezolimo I-Auxin Hormones I-Sodium Naphthoacetate Acid Naa-Na 98%Tc
Izakhiwo zomzimba namakhemikhali
Lo mkhiqizo yi-granule emhlophe, impushana noma i-crystalline powder; Ayinaphunga noma inephunga elincane, imnandi kancane futhi inosawoti. Lo mkhiqizo uncibilika kalula emanzini futhi uncibilika kancane ku-ethanol.
Izinzile emoyeni. Isixazululo sizinzile ku-pH ye-7-10. Incibilika kakhulu emanzini (53.0g/100ml, 25℃). Incibilika ku-ethanol (1.4g/100ml). Inani le-pH lesisombululo esinamanzi ngu-8. Amandla okuvimbela ukuvutshelwa namandla okubulala amagciwane abuthakathaka kune-benzoic acid. Ku-pH 3.5, isisombululo esingu-0.05% sivimbela ngokuphelele ukukhula kwemvubelo, futhi ku-pH 6.5, ukugxila kwesisombululo esingaphezu kuka-2.5% kuyadingeka.
Izinzuzo kanye nokubi
(1) I-solubility enhle kakhulu: ukuhlanzeka okuphezulu kwe-α-naphthalene acetate sodium inamanzi namafutha okuncibilika kabili, ngakho-ke ingenziwa ngokuzimela ibe amanzi, impushana, ukhilimu, i-granule namanye amafomu okulinganisa, okulula kakhulu ukuyisebenzisa futhi inomphumela omuhle kakhulu. Ngenxa yokuthi i-molecule eyodwa esixazululweni, ehlakazekile ngokulinganayo, kulula ukumuncwa izitshalo, futhi okuqukethwe okuvamile kwe-80% α-naphthalene acetate sodium kudinga ukuchithwa nge-ethanol, ukusetshenziswa akulula kakhulu. Ikhona esimweni samaqembu amangqamuzana ku-cream powder, ukuhlakazeka kubi, futhi umphumela awumuhle ngokwemvelo.
(2) Ukuhlanzeka okuphezulu, akukho ukungcola, imiphumela engeyona enobuthi: ukuhlanzeka okuphezulu kwe-α-naphthalene acetate sodium ukuhlanzeka okungaphezu kuka-98%, iqukethe inani elincane lamanzi, ayinakho okunye ukungcola okuphilayo, ngakho-ke ekusebenziseni kwayo ngempumelelo uhla lokuhlushwa ngokuvamile ngeke kubangele ukulimala kwezidakamizwa ezitshalweni, kanye nokusetshenziswa okujwayelekile kwe-α-naphthalene acetate, okubangela ukungcola okusebenzayo kwe-sodium, okubangela ukungcola okusebenzayo kwe-organic 20% ngenxa ye-organic ukungcola. ukulimala kwezidakamizwa emaqabunga amancane, efihlekile kanye nezithombo zezitshalo. Ukukhanya kubangela amachashaza amnyama, okusindayo kubangela ukufa, futhi kukhona ukungcola okuphilayo okubangela ukulimala emzimbeni womuntu kanye nemvelo. Noma yiluphi uhlobo lwesilawuli sokukhula kwesitshalo nesibulala-zinambuzane, ubumsulwa baso buhlobene nomphumela waso, njenge-sodium ehlanzekile kakhulu i-α-naphthalene acetate 5ppm(5μg/g) enomphumela omuhle, kuyilapho i-sodium α-naphthalene acetate evamile idinga ukufinyelela ku-20ppm(20μg/g) ukuze ibe nomthelela.
(3) Ukungahambi kahle okuhle: ukuhlanzeka okuphezulu kwe-α-naphthalene acetate sodium ingasetshenziswa ngokuhambisana nezilawuli eziningi zokukhula kwezitshalo, njenge: i-auxin, i-sodium nitrophenolate, izinto zokutshala izimpande, ama-fungicides, umanyolo, njll.; I-sodium alpha-naphthalene acetate evamile ngokuvamile ayisetshenziswa ngokuhlanganiswa.
Izici zokusebenza
Ukuhlanzeka okuphezulu i-α-naphthalene acetate sodium iyi-hormone yokukhulaisilawuli sokukhula kwezitshalongemiphumela emikhulu emithathu. Okokuqala ukukhuthaza ukwakheka kwezimpande ze-advental kanye nokwakheka kwezimpande, ngakho-ke ingasetshenziswa ukukhuthaza izimpande zembewu kanye ne-rooting, kodwa ukugxila kakhulu kungavimbela ukubola. Okwesibili ukukhuthaza ukunwetshwa kwezithelo nezimpande ze-tuber, ngakho-ke ingasetshenziswa njengento yokwandisa, futhi ukuhlolwa kwensimu kuye kwafakazela ukuthi kungandisa kakhulu isivuno futhi kuthuthukise izinga lamapentshisi enkawu, amagilebhisi, ikhabe, ukhukhamba, utamatisi, upelepele, isitshalo seqanda, amapheya, ama-apula. Ngesikhathi esifanayo, ikhuthaza ukwanda okusheshayo kwamangqamuzana, futhi izinga lokukhula kwe-solanum ephathwayo likhiqiza izinguquko eziyisimangaliso. Umphumela wamakhowe ubaluleke kakhulu futhi awunciphisi ikhwalithi yesithelo. Okwesithathu ukuvimbela izimbali nezithelo eziwayo, ezinomsebenzi wokulwa nokuwa. Ngaphezu kwalokho, iphinde ibe nemisebenzi ye-auxin evamile, njengokukhuthaza ukukhula, ukugqugquzela ukuhlanganiswa kwe-chlorophyll, nokukhuthaza ukuhlukaniswa kwehlumela nezimbali. Ngakho-ke, inomphumela wokukhuthaza ukuqhakaza kwezimbali nezithelo, ukukhuthaza amagatsha namaqabunga aluhlaza, ukwandisa isivuno kanye nokwenza ngcono izinga, nokwenza ngcono ukumelana kwezitshalo nesomiso, amakhaza kanye nendawo yokulala.
Indlela yokusebenzisa
Indlela yokusetshenziswa kokuhlanzeka okuphezulu kwe-α-naphthalene acetate sodium
(1) Sebenzisa yedwa
Ukuhlanzeka okuphezulu kwe-sodium α-naphthalene acetate kungalungiswa ngokuhlukana emanzini, ukhilimu, impushana nezinye izinhlobo zemithamo zokukhuthaza ukukhula, ukuqothula izimpande, ukulondolozwa kwezimbali, ukugcinwa kwezithelo nokunye. Umthamo wokusetshenziswa okukodwa: 2 amagremu kuya ku-30 kilograms wamanzi. Isikhumbuzi esikhethekile: inani elikhulu lithambekele ekulimaleni kwezidakamizwa.
(2) Isetshenziswa ngokuhambisana ne-sodium nitrophenolate
Ukuhlanzeka okuphezulu kwe-alpha-naphthalene acetate sodium kungahlanganiswa ne-nitrophenolate ye-sodium, i-hormone yokukhula, isikhunta, umanyolo, njll. i-nitrophenolate, kodwa futhi ibe nomthelela we-sodium α-naphthalene acetate, ukufeza umphumela ophindwe kabili ngesigamu somzamo.
Isicelo
Indlela yokwenza
Ukuhlanzeka okuphezulu kwe-sodium naphthalene acetate iyisilawuli sesitshalo se-auxin, esingena emzimbeni wesitshalo ngamaqabunga, isikhumba esithambile nembewu yezitshalo, futhi sithuthelwa ezingxenyeni zokukhula okunamandla (amaphuzu okukhula, izitho ezincane, izimbali noma izithelo) ngokugeleza kwezakhi. I-sodium naphthalene acetate ngokusobala yakhuthaza ukuthuthukiswa kwephuzu lempande (impuphu yezimpande). Ingakha izimbali, ivimbele isithelo esiwayo, yakhe izithelo ezingenambewu, ikhuthaze ukuvuthwa kusenesikhathi futhi yandise isivuno. Phakathi naleso sikhathi, i-sodium naphthalene acetate ingaphinde ithuthukise amandla okumelana nesomiso, ukumelana nokubanda, ukumelana nezifo, ukumelana ne-saline-alkali kanye nokumelana nomoya oshisayo omile wezitshalo. Ukuhlanzeka okuphezulu kwe-sodium naphthalene acetate kwahlolwa eJapane, eTaiwan nakwezinye izindawo, futhi umphumela wokusetshenziswa kwawo wawungcono kakhulu kunalowo we-sodium naphthalene acetate evamile.
Indlela yokuhlonza
(1) Ngemva kokuthatha cishe u-0.5g walo mkhiqizo bese wengeza u-10ml wamanzi ukuze uhlakaze, isixazululo sabonisa ukusabela okuhlukile phakathi kukasawoti we-sodium ne-benzoate.
(2) I-spectrum yokumunca ukukhanya kwe-infrared yalo mkhiqizo kufanele ihambisane ne-spectrum yokulawula.
Ukuhlola inkomba
Ph thatha i-1.0g yalo mkhiqizo, engeza u-20ml wamanzi ukuze uhlakaze, engeza amaconsi angu-2 esisombululo senkomba ye-phenolphthalein; Uma ibonisa okubomvu okukhanyayo, engeza isisombululo se-sulfuric acid titration (0.05mol/L)0.25ml, okubomvu okukhanyayo kufanele kunyamalale; Uma ingenambala, engeza i-sodium hydroxide titrant (0.1mol/L)0.25ml, kufanele ibonise okubomvu okukhanyayo.
Thatha lo mkhiqizo, womile ku-105 ℃ ukuze ube nesisindo esiqhubekayo, ukulahlekelwa isisindo akufanele kudlule u-1.5%.
Insimbi Enzima Thatha u-2.0g walo mkhiqizo, engeza u-45ml wamanzi, ugovuze ngokuqhubekayo, engeza u-5ml we-dilute hydrochloric acid, isihlungi, uhlukanise u-25ml we-filtrate, hlola ngokomthetho, okuqukethwe kwensimbi esindayo akufanele kudlule izingxenye ezingu-10 esigidini ngasinye.
Thatha i-1g ye-sodium carbonate ye-anhydrous ye-arsenic usawoti, uyisakaze phansi futhi uzungeze i-crucible, bese uthatha u-0.4g walo mkhiqizo, uwubeke ku-anhydrous sodium carbonate, uyimanzise ngamanzi amancane, emva kokumisa, uyishise ngomlilo ophansi ukuze i-carbonize it, bese uyishisa ku-500 ~ 600 ℃ ku-500 ~ 600 ℃ ukuze uyipholise ngokuphelele, i-hydroic chloric acid, ipholile ngokuphelele, i-hydroic chloric acid. 23ml wamanzi wokuwahlakaza, kufanele ahlangabezane nezidingo ngokomthetho (0.0005%).
Ukuzimisela kokuqukethwe
Thatha cishe u-1.5g walo mkhiqizo, ukale kahle, uwubeke kufaneli yesihlukanisi, engeza u-25ml wamanzi, u-50ml we-ether kanye namaconsi angu-2 e-methyl orange indicator liquid, i-titrate nge-hydrochloric acid titrant (0.5mol / L), unyakazisa ngamaconsi kuze kube yilapho ungqimba lwamanzi lubomvu ngokusawolintshi; Hlukanisa isendlalelo samanzi bese usibeka ebhodleleni elicijile ngepulaki. Geza ungqimba lwe-ether ngamanzi angu-5ml, wengeze i-ether engu-20ml ebhodleleni le-conical, qhubeka u-titration nge-hydrochloric acid titration solution (0.5mol/L), futhi unyakazise ngamaconsi kuze kube ungqimba lwamanzi lubonisa umbala obomvu owolintshi oqhubekayo. I-1ml ngayinye ye-hydrochloric acid titrant (0.5mol/L) ilingana no-72.06mg we-C7H5NaO2.
