4-氨基丁酸制备

1. 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。
