Methyl p-toluenesulfonate hantida kiimikada

Methyl 4-toluenesulfonate, oo sidoo kale loo yaqaan methyl p-toluenesulfonate (methylp-toluenesulfonate), waa dhexdhexaad kiimiko ah oo muhiim ah, oo inta badan loo isticmaalo soo saarista dheeha iyo isku-dhafka organic, sida diyaarinta buug-gacmeedka methylation alaabta ceeriin. Methyl 4-toluenesulfonic acid sidoo kale waxaa loo isticmaali karaa sida reagent methylation xulashada ee isku-dhafka organic, loo isticmaalo soo saarista midabada iyo isku-dhafka organic, oo loo isticmaalo diyaarinta alaabta ceeriin ee methylation, reagent methylation xulashada iyo kicinta isku-dhafka organic.

crystal cad. Barta dhalaalka 28-29â, barta karkarinta 292â, 146-147â (1.2kPa), cufnaanta qaraabo 1.231 (20/4â). Ku milma ethanol, ether, benzene, oo aan biyo lagu milmin. Hygroscopic

Laga soo bilaabo falcelinta p-toluene sulfonyl chloride oo leh methanol. Isku qas p-toluene sulfonyl chloride iyo methanol, si tartiib ah ugu dar 25% sodium hydroxide xal, heerkulka waxaa lagu xakameynayaa ka hooseeya 25â, pH 9, jooji ku darista alkali, Kiimikada sii wad inaad walaaqdo 2h, ka bax habeen. Dareen-celinta lakabka hoose ayaa la qaaday, lakabka sare waxaa laga soo saaray benzene, iyo xalalka la soo saaray waxaa lagu daray lakabka hoose ka dib markii dib loo warshadeeyo benzene, lagu dhaqay biyo iyo 5% xal carbonate potassium markeeda, iyo alaabta la dhammeeyey waxaa lagu helay nadiifinta vacuum. ka dib marka la qalajiyo.
