Methyl p-toluenesulfonate meatotino tau vailaau

Methyl 4-toluenesulfonate, e taʻua foi o le methyl p-toluenesulfonate (methylp-toluenesulfonate), o se vailaʻau vailaʻau taua tele, e masani ona faʻaaogaina i le gaosiga o vali ma le faʻaogaina o meaola, e avea o se Tusi Suʻesuʻega o le methylation mea mata. Methyl 4-toluenesulfonic acid e mafai foi ona faʻaaogaina e avea o se methylation reagent filifilia mo le faʻaogaina o meaola, faʻaaogaina i le gaosiga o vali ma faʻasologa o meaola, faʻaaogaina mo le saunia o mea e faʻaaogaina ai le methylation, filifili methylation reagent ma catalyst mo le faʻaogaina o meaola.

tioata paepae. Liu liusuavai 28-29â, vaipuna 292â, 146-147â (1.2kPa), fa'atusatusaga 1.231 (20/4â). Solu i le ethanol, eter, benzene, e le mafai ona solu i le vai. Hygroscopic.

Mai le tali ole p-toluene sulfonyl chloride ma le methanol. Faafefiloi le p-toluene sulfonyl chloride ma le methanol, faaopoopo lemu le 25% sodium hydroxide solution, o le vevela e pulea i lalo ole 25â, i le pH 9, taofi le faʻaopoopoina o le alkali, Chemicalbook faʻaauau pea ona faʻaoso 2h, alu i le po. O le vaega pito i lalo o mea e faʻafefe ai na ave, o le vaega pito i luga na maua mai i le benzene, ma o le vaifofo na faʻapipiʻiina na tuʻufaʻatasia ma le vaega pito i lalo pe a uma ona toe faʻaaogaina le benzene, fufulu i le vai ma le 5% potassium carbonate solution i le isi itu, ma o le oloa maeʻa na maua e ala i le vacuum distillation. ina ua uma ona faamago.
