Taw qhia
Isovaleraldehyde, propylene glycol, acetal. Nws tau txais los ntawm acetal cov tshuaj tiv thaiv ntawm isovaleraldehyde thiab propylene glycol.
Isovaleraldehyde propylene glycol acetal muaj toxicity tsawg, tsis muaj xim thiab tsw, thiab ruaj khov hauv huab cua. Nws ruaj khov nyob rau hauv acidic tej yam kev mob tab sis decomposes nyob rau hauv alkaline tej yam kev mob.
Muaj ntau qhov chaw thov rau isovaleraldehyde, propylene glycol, acetal. Nws yog dav siv los ua ib qho tseem ceeb hnyav thiab reagent hauv organic synthesis. Qhov thib ob, nws tuaj yeem siv los ua cov khoom siv ntxiv rau hauv thaj chaw xws li txheej, dyes thiab plastics los txhim kho cov khoom lag luam.
Txoj kev npaj isovaleraldehyde propylene glycol acetal yog tsuas yog tau los ntawm cov tshuaj tiv thaiv ntawm isovaleraldehyde thiab propylene glycol. Cov tshuaj tiv thaiv feem ntau yog ua nyob rau hauv acidic tej yam kev mob, xws li acid-catalyzed los yog nrog acidic immobilization catalysts. Cov tshuaj tiv thaiv no yuav tsum tau tswj qhov kub thiab txias thiab lub sij hawm tshuaj tiv thaiv kom nce yield thiab purity.
Cov ntaub ntawv kev nyab xeeb: Isovaleraldehyde propylene glycol acetal yog cov tshuaj lom neeg tsawg. Tab sis nws tseem yog ib qho irritant thiab tiv nrog daim tawv nqaij thiab qhov muag yuav tsum tau zam. Kev tiv thaiv tsim nyog yuav tsum tau ua, xws li hnav hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv, thaum siv. Thaum noj los yog nqus tau, nrhiav kev kho mob tam sim ntawd.
