Umkhiqizi Intengo Enhle I-Alpha Methyl Styrene CAS 98-83-9

incazelo emfushane:

I-2-Phenyl-1-propene, eyaziwa nangokuthi i-Alpha Methyl Styrene (efushanisiwe ngokuthi i-a-MS noma i-AMS) noma i-phenylisopropene, iwumkhiqizo wokukhiqizwa kwe-phenol ne-acetone ngendlela ye-cumene, ngokuvamile iwumkhiqizo we-phenol ngethani elilodwa elingu-0.045t α-MSY ongenalutho olunemibala e-Methyl-MS. I-molecule iqukethe iringi ye-benzene kanye ne-alkenyl esikhundleni seringi ye-benzene.I-Alpha Methyl Styren ijwayele ukwenziwa i-polymerization uma ishisisa. I-Alpha Methyl Styren ingasetshenziswa ekukhiqizeni okokugqoka, ama-plasticizers, nanjenge-solvent ku-organic.

I-Alpha Methyl Styrene iwuketshezi olungenambala. Ayincibiliki emanzini futhi iminyene kancane kunamanzi. Iphoyinti elikhanyayo ngu-115°F. Ingase ibe nobuthi obuncane ngokumunca, ukuhogela kanye nokumunca isikhumba. Izihwamuko zingase zibe i-narcotic ngokuhogela. Isetshenziswa njenge-solvent kanye nokwenza amanye amakhemikhali.

Izicelo ze-AMS

I-Alpha Methyl Styrene ingasetshenziswa njenge-monomer yama-polymers njengerabha ye-toluene-butadiene kanye namapulasitiki okushisa aphezulu. Ingase futhi isetshenziselwe ukulungisa okunamathelayo, okunamathelayo okuncibilika okushisayo, ama-plasticizers kanye ne-synthetic musk. E-Japan, u-90% we-α-methylstyrene usetshenziswa njengesilungisi se-ABS resin, kanti enye isetshenziswa njengesixazululi kanye nezinto ezingavuthiwe zokwenziwa kwe-organic.

1.I-Intermediate ye-ABS plastics, i-Styrene - i-Butadiene irabha, i-Polystyrene, i-Styrene - i-Acrylonitrile Resins, i-Perfumery, i-Polyalphamethyl Styrene, i-Polyester resins.
2.Polymerization monomer, ikakhulukazi for polyester.
I-3.α-Methylstyrene akuyona i-styrenic monomer ngomqondo oqinile. Ukushintshanisa i-methyl ochungechungeni oluseceleni, esikhundleni sendandatho enephunga elimnandi, kumodela ukusebenza kabusha kwayo ku-polymerization. Isetshenziswa njenge-monomer ekhethekile kuma-resin e-ABS, okokunamathela, ama-polyester resins, nezinamatheliso ezincibilika ngokushisayo. Njenge-copolymer ku-ABS ne-polystyrene, inyusa ukumelana nokushisa komkhiqizo. Ezimbotsheni nasezinsikeni, ilinganisela amazinga okusabela futhi ithuthukise ukucaca.
