Daim ntawv thov
1. Sodium ethoxide feem ntau yog siv los ua lub hauv paus muaj zog thiab catalyst hauv cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv Claisen condensations thiab esterification cov tshuaj tiv thaiv.
2. Sodium ethoxide CAS 141-52-6 ua tus neeg sawv cev ethoxylating thiab reagent hauv kev tsim tshuaj, agrochemicals, thiab biofuels.
3. Sodium ethoxide yog ua haujlwm nyob rau hauv polymer chemistry thiab ua kom qhuav tus neeg sawv cev rau cov kuab tshuaj.
Cia thiab ceev faj
1. Store Sodium ethoxide in a tightly sealed, moisture-proof container under an inert atmosphere (eg, nitrogen or argon) in a cool, dry, well-ventilated, and dedicated area away from heat and incompatible materials.
2. Khaws Sodium ethoxide CAS 141-52-6 nruj me ntsis kom deb ntawm dej, acids, cawv, thiab oxidizing cov neeg ua haujlwm kom tsis txhob muaj kev kub ntxhov, hluav taws kub, lossis tawg.
3. Kov Sodium ethoxide nrog kev saib xyuas hnyav siv cov cuab yeej tiv thaiv tus kheej tsim nyog thiab cov txheej txheem tsis muaj dej; Nws yog corrosive heev, hygroscopic, thiab flammable.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm tam sim ntawd thiab cais thaj chaw. Tshem tawm qhov hluav taws kub, xyuas kom muaj cua. Tsuas yog cov neeg ua haujlwm tau txais kev cob qhia hauv cov khoom siv tshuaj tiv thaiv tag nrho thiab tus kheej -cov cuab yeej ua pa yuav tsum mus ze.
2. Tsis txhob siv dej los yog ua npuas dej. Npog CAS 141-52-6 qhov nchuav nrog cov xuab zeb qhuav los yog lwm yam inert, uas tsis yog-combustible absorbent nyob rau hauv inert cua yog ua tau. Sau rau hauv ib lub thawv ntim, sau npe rau cov khoom pov tseg uas muaj kev phom sij heev.
3. Ua tib zoo saib xyuas cov khoom seem nrog cov cawv qhuav ua raws li kev tswj hwm dilution. Tiv thaiv kom tsis txhob muaj kev sib cuag nrog dej lossis nkag mus rau hauv cov kav dej. Yuav tsum muaj kev pov tseg pov tseg uas muaj kev phom sij.
Cov ntaub ntawv kev nyab xeeb
1. Sodium ethoxide ua rau cov tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa ua pa. Nws reacts hnyav nrog dej, tso cov nplaim hluav taws ethanol thiab corrosive sodium hydroxide.
2. Sodium ethoxide CAS 141-52-6 yog cov nplaim taws heev, tuaj yeem ua rau kub hnyiab hauv huab cua, thiab decomposes rau cov pa phem. Nws yog tshuaj lom rau cov dej hauv dej.
3. Hnav cov cuab yeej tiv thaiv tag nrho (tshwj xeeb- hnab looj tes tiv thaiv, tsom iav, lub ntsej muag daim npog ntsej muag, lub tshuab ua pa, hluav taws kub- lub tsho tiv thaiv kab mob) thiab ua haujlwm hauv lub hnab looj tes lossis fume hood.
