补充资料:γ-氨基丁酸
分子式:C4H9NO2
分子量:103.12
CAS号:56-12-2

性质:白色或近白色结晶性粉末。熔点203℃(分解)。极易溶于水,微溶于热乙醇,不溶于冷乙醇、乙醚和苯。熔化时分解成吡咯烷酮和水。

制备方法:有合成法和发酵法。1.合成法由吡咯烷酮开环制得。将生石灰用蒸馏水消化成石灰乳,抽入水解反应釜,加吡咯烷酮,升温至125-130℃,反应压力保持在0.29MPa,保温反应10-14h以上。反应结束后降温至30℃出料过滤,用蒸馏水洗涤。滤液加碳酸氢铵,直至无钙离子检出,再加活性炭在80℃保温脱色30min,60℃过滤,用蒸馏水洗,洗液与滤液合并,在60℃减压浓缩至析出结晶,加入乙醇,冷却、过滤、干燥,得成品,收率为85%以上。2.发酵法 使用大肠杆菌作为菌种。发酵培养基为麸皮水解液、玉米浆、蛋白胨、硫酸镁和氯化钠等。以豆油为消沫剂,用量约为0.1%,发酵单位约为100酶单位/ml发酵液。在提炼过程中,利用大肠杆菌脱羧酶的作用,将L-谷氨酸转化为γ-氨酪酸在水溶液中能解离成阳离子的特性,采用强酸性苯乙烯系阳离子交换树脂进行离子交换,氨水洗脱,提取,再经树脂纯化,浓缩、结晶、干燥后即得成品。

用途:医药中间体。4-氨基丁酸有降低血脂作用适用于治疗和预防各类型肝昏迷。治疗小儿麻痹症、脑溢血,并可作煤气中毒解毒剂。也用于生化研究和有机合成。
