Liquid formaldehyde is a mass chemical product with a wide range of uses, simple production process and sufficient supply of raw materials. It is the backbone of the downstream product tree of methanol. The annual output of the world is about 25 million tons, and about 30% of the methanol is used to produce formaldehyde. But formaldehyde is a low concentration of water solution, from the economic point of view is not convenient for long-distance transportation, so generally set up factories near the main consumer market, import and export trade is very little.

In addition to the price of liquid formaldehyde can be directly used as disinfection, sterilization, preservatives, mainly used in organic synthesis, synthetic materials, coatings, rubber, pesticides and other industries, its derivatives are mainly polyformaldehyde, polyformaldehyde, phenolic ester, urea-formaldehyde ester, amino tree ester, Uloto products and polyols. The wood-based panel industry is developed, the demand for formaldehyde is very large.
