Daim ntawv thov
1. Isovanillin feem ntau yog siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, tshwj xeeb tshaj yog ua ntej hauv cov tshuaj tag nrho cov synthesis ntawm morphine. Nws kuj yog dav siv los ua tshuaj nruab nrab.
2. Isovanillin CAS 621-59-0 ua lub zog thiab thim rov qab inhibitor ntawm aldehyde oxidase (AO), nrog tus nqi Ki ntawm 0.664 μM. Nws tau raug tshawb xyuas rau ntau lub luag haujlwm lom neeg, suav nrog tshuaj tua kab mob, tshuaj tua kab mob, thiab tshuaj tiv thaiv kab mob.
3. Cov ntawv thov ntawm Isovanillin kuj suav nrog nws siv hauv kev lag luam zaub mov thiab dej haus, hauv kev tsim cov tshuaj tsw qab hluavtaws, thiab ua cov tshuaj reagent hauv kev tshawb fawb biochemical.
Cia thiab ceev faj
1. Khaws Isovanillin nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua, tiv thaiv los ntawm lub teeb thiab cua sov. Pom zoo cia kub sib txawv: hmoov cov ntaub ntawv tuaj yeem khaws cia ntawm -20℃rau 3 xyoos lossis 4℃rau 2 xyoos; cov kev daws teeb meem hauv cov kuab tshuaj yog qhov zoo tshaj plaws khaws cia ntawm -80℃rau 6 lub hlis lossis -20℃rau 1 lub hlis. Rau kev siv ib txwm siv, qhov chaw txias, tsaus nti hauv qab 15℃feem ntau qhia.
2. Khaws Isovanillin kom deb ntawm cov khoom muaj zog oxidizing thiab cov hauv paus muaj zog, vim nws tsis sib haum nrog cov ntaub ntawv no. Nws kuj yog qhov nkag siab rau lub teeb, huab cua, thiab lub sijhawm ntev ntawm cov huab cua, uas tuaj yeem degrade nws purity.
3. Ib txwm siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) suav nrog tshuaj lom neeg - hnab looj tes tiv thaiv (xws li nitrile), tsom iav kev nyab xeeb nrog cov ntaub thaiv npog sab lossis daim npog ntsej muag, thiab cov khaub ncaws tiv thaiv thaum tuav Isovanillin kom tsis txhob muaj plua plav thiab tiv thaiv daim tawv nqaij, qhov muag, lossis khaub ncaws. Tsuas yog siv qhov cua kom txaus los yog hauv lub hood fume.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav, zam cov plua plav tsim, thiab xyuas kom muaj cua txaus. Muaj Isovanillin siv inert, tsis yog - cov khoom siv hluav taws xob uas tsis muaj zog (xws li, lub ntiaj teb diatomaceous, universal binder) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej ntws.
2. Ua tib zoo cheb cov khoom uas spilled Isovanillin siv huv si, tsis yog - cov cuab yeej ua kom tawg lossis siv qhov tawg- pov thawj lub tshuab nqus tsev. Rau cov khoom seem, siv cawv los txhuam qhov chaw thiab khoom siv. Muab tag nrho cov ntaub ntawv khaws tseg thiab cov khoom tsis huv rau hauv cov thawv ntim khoom ntim, sau cov tshuaj khib nyiab pov tseg kom raug raws li hauv zos, xeev, thiab tsoomfwv cov cai tswjfwm ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum yog Isovanillin CAS 621-59-0 hnav PPE tsim nyog, suav nrog cov hnab looj tes tiv thaiv tshuaj thiab cov khaub ncaws tiv thaiv, thaum ntxuav. Isovanillin tsis raug tswj raws li cov khoom siv phom sij rau kev thauj los ntawm qee qhov kev faib tawm.
Cov ntaub ntawv kev nyab xeeb
1. Isovanillin raug cais raws li cov lus ceeb toom cov lus ceeb toom raws li GHS. Nws ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335). Tshaj tawm mob toxicity muaj xws li intraperitoneal LD50 ntawm 1,276 mg / kg hauv nas.
2. Isovanillin yog combustible nrog ib tug flash point ntawm 179 degree. Nws thermal decomposition los yog combustion ua rau cov pa phem thiab irritating pa, nrog rau cov pa roj carbon oxides. Isovanillin CAS 621-59-0 yog ruaj khov nyob rau hauv cov kev pom zoo cia tab sis yuav tsum tau tiv thaiv los ntawm muaj zog oxidizing neeg sawv cev.
3. Nco ntsoov sab laj nrog Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Isovanillin kom tiav cov ntaub ntawv txaus ntshai, ua ntej- txheej txheem pab (P305+P351+P338 rau qhov muag, P302+P352 rau daim tawv nqaij, P304+P340 rau kev nqus pa), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P261 (tsis txhob ua pa plua plav), P264 (ntxuav daim tawv nqaij kom huv si tom qab tuav), P280 (hnav looj hnab looj tes tiv thaiv qhov muag), thiab P337+P313 (yog tias qhov muag khaus tshwm sim, mus ntsib kws kho mob).
