Preparation process of high-concentration compound amino acid injection
A technology for the preparation of compound amino acids and injections, which is applied in the field of preparation of high-concentration compound amino acid injections. It can solve the problems of excessive decline in the content of tryptophan, unstable quality of amino acid injections, and yellowish color of high-concentration compound amino acid injections. and other problems, to achieve stable product quality, avoid yellowing of color and content decline, and good dissolution effect

Embodiment 1
[0062] Follow the steps below to prepare high-concentration compound amino acid injection:
[0063] 1. Preparation tank and pipeline pretreatment
[0064] (1) Passivation treatment: prepare a proper amount of 1% sodium hydroxide solution at 70°C and circulate it for 40 minutes to clean the concentrated preparation tank, thin preparation tank and preparation pipeline, dilute the lotion with water for injection, and rinse it. The test results of the water sample meet the requirements according to the standard of water for injection; prepare an appropriate amount of 8% nitric acid solution at 50°C and circulate it for 60 minutes to clean the concentrated preparation tank, dilute preparation tank and preparation pipeline, dilute the lotion with water for injection, rinse, and take After flushing, the test results of the water samples meet the requirements according to the standard of water for injection;
[0065] (2) Removal of metal ions: add an appropriate amount of water for i...
