Keokeo keokeo. Ka helu heheʻe 28-29â, wahi paila 292â, 146-147â (1.2kPa), mānoanoa pili 1.231 (20/4â). Hiki ke hoʻoheheʻe ʻia i ka ethanol, ether, benzene, hiki ʻole ke hoʻoheheʻe ʻia i ka wai. Hygroscopic.
Mai ka hopena o ka p-toluene sulfonyl chloride me ka methanol. E hoʻohui i ka p-toluene sulfonyl chloride a me ka methanol, e hoʻohui mālie i ka 25% sodium hydroxide solution, ke hoʻomalu ʻia ka mahana ma lalo o 25â, i ka pH 9, hoʻōki i ka hoʻohui ʻana i ka alkali, Chemicalbook e hoʻomau i ka hoʻoulu ʻana i 2h, waiho i ka pō. Lawe ʻia ka papa haʻahaʻa haʻahaʻa, lawe ʻia ka papa luna me benzene, a ua hui pū ʻia ka hopena i unuhi ʻia me ka papa haʻahaʻa ma hope o ka hana hou ʻana i ka benzene, holoi ʻia me ka wai a me 5% potassium carbonate solution ma ka huli ʻana, a loaʻa ka huahana i hoʻopau ʻia e ka distillation vacuum. mahope o ka maloo ana.
