L-色氨酸是人体必须的八种氨基酸之一,在医药方面主要用于配制复方氨基酸输液等营养制剂,也可单独应用于治疗抑郁症等疾患,在食品工业和饲料工业领域大量用于要素饮食及饲料的添加剂。此外,L-色氨酸还是合成多肽药物的基本原料,它的应用日益广泛,前景广阔。目前世界上L-色氨酸年产量约200吨,预计今后将有大幅度增长。目前国内所需的L-色氨酸几乎全部依赖进口。武汉制药厂为改变我同进口L-色氨酸的局面,利用本厂氯霉素生产原料对硝基乙苯的副产物——邻硝基乙苯为起始原料,经还原、闭环、
L-tryptophan is one of the eight essential amino acids that the human body needs. It is mainly used for the preparation of nutritional preparations such as compound amino acid infusion in medicine. It can also be used alone in the treatment of diseases such as depression. It is widely used in the food industry and feed industry Elements diet and feed additives. In addition, L-tryptophan is still the basic raw material of synthetic peptide drugs, its application is more and more extensive and has a bright future. At present, the annual production of L-tryptophan in the world is about 200 tons, and it is expected that there will be a substantial increase in the future. At present, almost all the L-tryptophan needed in the country is imported. Wuhan Pharmaceutical Factory to change my situation with the import of L-tryptophan, the use of chloramphenicol raw materials for the production of nitrobenzene by-product - o-nitrobenzene as a starting material, the reduction, closed-loop,
