Problems solved by technology

[0002] Fatty Alcohol is an important intermediate of various chemicals, household products, etc., and its demand has increased greatly in recent years; we have been committed to improving the quality of washing liquid for a long time. The preparation of washing liquid requires fatty alcohol, and the washing liquid phase Compared with washing powder and other washing materials, it has the advantages of easy dissolution, pre-configuration, and good low-temperature cleaning effect, and it will definitely be popularized in a large area. Phosphorus washing liquid; due to the limitation of the fatty alcohol of the raw material of the washing liquid, the washing liquid prepared by using the existing fatty alcohol is chemically corrosive, easy to use and will cause certain corrosion to the washing object; the decontamination effect also needs to be improved
