Methyl p-toluenesulfonate taonga matū

2022-06-22
Ko te Methyl 4-toluenesulfonate, e kiia ana ko te methyl p-toluenesulfonate (methylp-toluenesulfonate), he takawaenga matū pararopi nui, e whakamahia ana i te nuinga o te waa ki te hanga waikano me te whakahiato waro, hei whakarite pukapuka matū mo te methylation rauemi mata. Ka taea hoki te whakamahi i te waikawa methyl 4-toluenesulfonic hei reagent methylation whiriwhiri mo te whakahiato waro, whakamahia i roto i te hanga o te waikano me te whakahiato waro, whakamahia mo te whakarite i te methylation raw rauemi, whiriwhiri methylation tauhohenga me te whakakōkī mo te kōtuitanga organic.


Kiriata ma. Ira whakarewa 28-29â, ira koropuha 292â, 146-147â (1.2kPa), kiato whanaunga 1.231 (20/4â). Ka whakarewahia ki te waiwaro, te etera, te benzene, kare e rewa ki te wai. Hygroscopic.


Mai i te tauhohenga o te p-toluene sulfonyl chloride me te mewaro. Whakaranuhia te p-toluene sulfonyl chloride me te methanol, me ata taapirihia te 25% konutai wairewa wairewa, ka whakahaeretia te pāmahana i raro iho i te 25â, ki te pH 9, ka mutu te taapiri i te kawakore, ka whakaoho tonu te Chemicalbook 2h, waiho mo te po. I tangohia nga tauhohenga paparanga o raro, ka tangohia te paparanga o runga me te benzene, ka honoa te otinga tangohanga me te paparanga o raro i muri i te hangarua i te benzene, ka horoia ki te wai me te 5% konupora konupora konupora ka huri, ka riro te hua kua oti ma te whakamarumaru korehau. i muri i te whakamaroke.
