Maleic anhydride/CAS:108-31-6
Tsananguro pfupi:
Zita rechigadzirwa: Maleic anhydride
CAS:108-31-6
MF:C4H2O3
MW:98.06
MAUMBIRWO:
Maleic Anhydride (MAN) chinhu chinobva mumakemikari chine fomura yemakemikari C4H203. Ndiyo acid anhydride ye maleic acid uye kana iri yakachena, chinhu chakasimba chisina ruvara kana chichena chine hwema hwe acrid. Maleic anhydride imorekuru inoshamisa nekuti ine mhando mbiri dzemakemikoro zvinoita kuti ive yakakosha mukugadzirwa kwemakemikari uye mashandisirwo awo.
Maleic Anhydride imhando yemakemikari inoshanda zvakasiyana-siyana uye inoshandiswa muindasitiri yemakemikari. Inonyanya kushandiswa sechikafu chekudya mukugadzira maresini epolyester asina kuzara (UPR).
Maresini aya anoshandiswa mukushandiswa kwegirazi uye mukushandiswa kusina kusimbiswa. Mashandisirwo eUPR anosanganisira kushandiswa kwakasiyana-siyana mukuvaka, indasitiri yemugungwa uye yemotokari.

Kushandiswa
Maleic Anhydride chinhu chinoshandiswa mukugadzira maresini epolyester asina kuguta. Chinoshandiswawo mumhando dzakasiyana siyana; chinoshandiswawo mumatenside ekugadzira, mishonga yezvipembenene, mishonga yesora uye mishonga yefungi.
Maleic anhydride inoshandiswa muDiels-Alder syntheses (se dienophile), kugadzirwa kwealkyd-type of resins, dye intermediates, pharmaceuticals, Agricultural chemicals (maleic hydrazide, malathion), mu copolymerization reactions.
