Chemical Properties:

Maleic Anhydride (MAN) yog ib qho organic compound nrog cov tshuaj formula C4H203. Nws yog acid anhydride ntawm maleic acid thiab nyob rau hauv nws cov ntshiab lub xeev nws yog ib tug tsis muaj kob los yog dawb khoom nrog ib tug acrid tsw. Maleic anhydride yog qhov zoo tshaj plaws molecule nyob rau hauv uas nws muaj ob hom tshuaj ua haujlwm ua rau nws muaj txiaj ntsig zoo inchemical synthesis thiab kev siv.

Maleic Anhydride yog ib qho tshuaj lom neeg ua haujlwm nruab nrab nrog cov ntawv thov hauv ntau qhov kev lag luam tshuaj. Nws qhov kawg siv yog raws li cov khoom noj khoom haus hauv kev tsim cov khoom siv tsis zoo polyester resins (UPR).
Cov resins no yog siv ob qho tib si hauv iav-reinforced thiab hauv cov ntawv thov tsis muaj zog. Kev siv UPR kawg suav nrog ntau yam kev siv hauv kev tsim kho, kev lag luam marine thiab tsheb.
Tsis tas li ntawd, Maleic Anhydride tuaj yeem siv los ua cov khoom siv raw hauv kev tsim cov 1,4-butanediol (BDO), gamma-butyrolactone thiab tetrahydrofuran (THF). Nws yog ib qho tseem ceeb los qhia tias BDO yog ib qho ntawm cov tshuaj loj tshaj plaws hauv ntiaj teb hauv xyoo tas los.

Daim ntawv thov:

Hauv Diels-Alder syntheses (raws li dienophile), tsim cov alkyd-hom resins, dye intermediates, tshuaj, tshuaj ua liaj ua teb (maleic hydrazide, malathion), nyob rau hauv copolymerization tshuaj.

Maleic Anhydride yog heterocyclic compound siv nyob rau hauv kev tsim ntawm unsaturated polyester resins. Maleic Anhydride muaj ntau yam ntawm lwm yam kev siv; Nws yog siv nyob rau hauv hluavtaws tensides, insecticides, herbicides thiab fungicides.
