Description

technical field

[0001] The invention relates to a preparation process of lauromacrogol. Background technique

[0002] Lauromacrogol injection has become one of the main methods for treating varicose veins due to its high efficiency, safety and quickness. Varicose veins is a common and frequently-occurring disease of the venous system with a history of more than 150 years. When the existing technology is producing and preparing lauromacrogol, the yield is not high and the product is unstable. Contents of the invention

[0003] The object of the present invention is to provide a kind of lauromacrogol preparation technology.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] A preparation process of lauromacrogol, comprising the following steps:

[0006] Add dodecanol and potassium hydroxide into a clean, dry, and well-sealed autoclave, seal it, stir evenly, heat up to 100°C-120°C, vacuumize, the vacuum degree ...
