Propanoic acid

Propanoic acid, tseem hu ua n-propionic acid, yog peb -carbon carboxylic acid thiab luv - chainsaturated fatty acid nrog cov tshuaj formula CH3CH2COOH. Ntshiab propanoic acid yog cov xim tsis muaj xim, corrosive kua nrog pungent tsw.
Nws yog tsuas yog siv los ua zaub mov preservative thiab antifungal tus neeg sawv cev. Nws tseem tuaj yeem siv los ua cov viscosity inhibitor hauv npias thiab lwm yam khoom, cov kuab tshuaj rau nitrocellulose thiab plasticizer. Nws kuj tseem siv rau hauv kev npaj cov nickel plating daws, cov khoom noj khoom haus, thiab kev tsim cov tshuaj, tshuaj tua kab, thiab tshuaj tua kab mob, thiab lwm yam.

Kev siv tseem ceeb: Nws yog siv los ua tus neeg sawv cev esterification, hnyav rau nitrocellulose, plasticizer, tshuaj reagent, thiab npaj cov khoom xyaw zaub mov, thiab lwm yam.
Nws yog tsuas yog siv los ua zaub mov preservative thiab antifungal tus neeg sawv cev. Nws kuj tseem siv tau los ua viscosity inhibitor hauv npias thiab lwm yam khoom. Nws ua hauj lwm raws li ib qho hnyav thiab plasticizer rau nitrocellulose. Nws kuj tseem siv rau hauv kev npaj cov tshuaj nickel plating, zaub mov flavorings, thiab kev tsim tshuaj, tshuaj tua kab, thiab tshuaj tua kab mob.

【Operating Precautions】 Ua haujlwm nyob rau hauv ib qho chaw kaw nrog kev ua kom cua zoo. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug pom zoo tias cov neeg ua haujlwm hnav tus kheej - cua lim lim roj qhov ncauj qhov ntswg (ib nrab- lub ntsej muag lub ntsej muag), tshuaj tiv thaiv tsom iav, hnav khaub ncaws ua haujlwm tiv taus cov kua qaub thiab alkalis, thiab hnab looj tes roj hmab acid thiab alkali resistant. Khaws kom deb ntawm qhov hluav taws kub thiab qhov hluav taws kub, thiab txwv tsis pub haus luam yeeb hauv chaw ua haujlwm. Siv tawg- pov thawj qhov cua tshuab thiab khoom siv. Tiv thaiv kom tsis txhob muaj vapor nkag mus rau hauv huab cua ntawm qhov chaw ua haujlwm. Tsis txhob sib cuag nrog oxidants, reductants, thiab alkaline tshuaj. Ua tib zoo saib xyuas, thiab tiv thaiv kev puas tsuaj rau cov ntim thiab ntim. Muab cov khoom sib xws thiab qhov ntau ntawm cov hluav taws kub- cov khoom siv sib ntaus sib tua thiab cov cuab yeej siv thaum muaj xwm ceev rau cov dej xau. Cov thawv khoob tseem tuaj yeem muaj cov khoom tsis zoo.
