Cov kev siv ntawm maleic anhydride yog dab tsi?

Maleic anhydride (tseem hu ua cis-butenedioic anhydride) yog cov khoom siv tseem ceeb ntawm cov organic chemical raw, qeb thib peb ntawm cov anhydrides (tom qab phthalic anhydride thiab acetic anhydride). Nws feem ntau yog siv los tsim cov unsaturated polyesters thiab alkyd resins, thiab kuj pom cov ntawv thov hauv cov tshuaj tua kab, coatings, inks, lubricant additives, papermaking chemicals, textile finishing agents, thiab surfactants. Cov derivatives los ntawm maleic anhydride suav nrog 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, maleic acid, fumaric acid, thiab tetrahydrophthalic anhydride—txhua yam tshuaj organic thiab tshuaj zoo tseem ceeb.

Vim li cas ho xaiv Maleic Anhydride? Nws yog lub hauv paus ntawm cov polyester resins tsis muaj zog zoo tshaj plaws, ntxiv rau nws qhib ntau yam tshuaj lom neeg (BDO, THF, thiab lwm yam). Xa xov rau peb tam sim no kom tshawb nrhiav cov kev daws teeb meem MA uas haum rau koj txoj kev lag luam!
