Kaihanga Utu Pai Alpha Methyl Styrene CAS 98-83-9

whakaahuatanga poto:

Ko te 2-Phenyl-1-propene, e mōhiotia ana ko Alpha Methyl Styrene (e whakarāpopototia ana ko a-MS, ko AMS rānei) ko phenylisopropene rānei, he hua taha o te hanga o te phenol me te acetone mā te tikanga cumene, ko te tikanga he hua taha o te phenol mō ia tana 0.045t α-MS. He wai kore tae te Alpha Methyl Styren me te kakara kino. Kei roto i te ngota he mowhiti benzene me te alkenyl substituent i runga i te mowhiti benzene. Ka ngāwari te Alpha Methyl Styren ki te polymerization ina wera. Ka taea te whakamahi i te Alpha Methyl Styren ki te hanga paninga, plasticizers, me te whakarewa i roto i te waro.

He wai kore tae te Alpha Methyl Styrene. Kāore e wairewa i te wai, ā, he iti ake te mātotoru i te wai. Ko te pūmahana mura he 115°F. Tērā pea he paitini pakupaku ina horomia, ina manawahia, ina mimitihia hoki e te kiri. Tērā pea he narkotika ngā kohu ina manawahia. Ka whakamahia hei whakarewa, hei hanga hoki i ētahi atu matū.

Ngā tono o te AMS

Ka taea te whakamahi i te Alpha Methyl Styrene hei monomer mō ngā polymer pērā i te rapa toluene-butadiene me ngā kirihou pāmahana teitei. Ka taea hoki te whakamahi hei hanga paninga, hei whakapiripiri rewa wera, hei whakapūmau kirihou me te musk hangai. I Hapani, e 90% o te α-methylstyrene e whakamahia ana hei whakarerekētanga mō te kapia ABS, ā, ko te toenga e whakamahia ana hei whakarewa me te rauemi mata mō te hanga rauropi.

1. Waenga mō ngā kirihou ABS, Styrene - Butadiene rapa, Polystyrene, Styrene - Acrylonitrile Resins, Hinu Kakara, Polyalphamethyl Styrene, Polyester resins.
2. Te monomerization, inā koa mō ngā polyesters.
3. Ehara te α-Methylstyrene i te monomer styrenic i te tikanga tino tika. Ko te whakakapinga methyl i te mekameka taha, kaua i te mowhiti kakara, ka whakaōrite i tōna tauhohenga i roto i te polymerization. Ka whakamahia hei monomer motuhake i roto i ngā kapia ABS, ngā paninga, ngā kapia polyester, me ngā piripiri rewa-wera. Hei copolymer i roto i te ABS me te polystyrene, ka whakanui ake i te ātete wera-whakarerekētanga o te hua. I roto i ngā paninga me ngā kapia, ka whakaōrite i ngā tere tauhohenga me te whakapai ake i te mārama.
