Kupu Whakataki
whakataki
He ranunga o te methyl me te ethyl isomethyl violet ketone me te methyl me te ethyl ortho methyl violet ketone.
taiao
Ko te alpha isomethylprednisolone he puhui waro. He totoka karaihe papura. I te pāmahana rūma, he kakara kakara ahurei.
Ko te alpha isomethylprednisolone he ketone kakara. Ka puta mai i te tauhohenga methylation o te waipiro puru, ka kiia ko te ketone isomethyl violet. He whakakai kakara me te roopu ketone kei roto i tona hanganga ngota.
I te pāmahana rūma, he totoka, engari ka taea te rewa ma te whakamahana. Kare e rewa ki te wai, engari ka memeha ki etahi whakarewa pararopi penei i te waiwaro me te dichloromethane. He tairongo ki te marama, a ka taea te tauhohenga photolysis i raro i te whakamaarama rama ultraviolet.
Mo nga ahuatanga matū, ko te α – isomethylprednisolone he pūhui tauhohenga. Ka pa ki nga tauhohenga penei i te waikura, te whakaheke, te taapiri, me te whakakapi. Ka tauhohe ki etahi reagents electrophilic ki te hanga hua taapiri. Ka taea te protonated i te aroaro o nga waikawa kaha. Ka taea hoki te huri hei waikawa ketone na roto i nga tauhohenga waiora.
Tikanga whakaputa
Ko te tikanga e whai ake nei mo te hanga alpha isomethylprednisolone:
Te whakarite rauemi tuatahi: Whakaritehia nga rauemi tuatahi, tae atu ki te Isobutyl ketone me te Cyclohexanone. Ko enei pūhui e rua he mea nui mo te whakahiato o te α – isomethylprednisolone.
Tautuhinga huru tauhohenga: Reacte isodecanone me cyclohexanol i raro i nga tikanga e tika ana. Ko te tikanga tauhohenga noa ko te whakahaere i te tauhohenga i raro i nga tikanga waikawa, a ko nga whakakorikori waikawa e whakamahia nuitia ana ko te waikawa pungatara (H2SO4) me te waikawa phosphoric (H3PO4).
Nga mahi tauhohenga: Whakaranuhia tetahi nui o te isodecanone me te cyclohexanol, me te taapiri i te whakakorikori waikawa. Na, ka mahia te tauhohenga i te pāmahana e tika ana, me te awhe pāmahana e whakamahia ana ko te 50-70 nga nekehanga Celsius. Ko te tikanga he maha nga haora ki te tekau haora te wa tauhohenga.
Wehenga me te purenga: I muri i te otinga o te tauhohenga, ka purea te hua mai i te ranunga tauhohenga ma te whakamaarama me etahi atu tikanga wehe.
Te whakamaroketanga me te whakamaroke: Whakaparaa me te whakamaroke i te hua kua purea kia whiwhi ai i te hua alpha isomethylprednisolone whakamutunga.
