colorless transparent liquid, volatile, irritating odor, with tear. Melting Point -103.5 °c. Boiling point of 59 degrees C (59.1 degrees C). Relative density (d20)1. 07. Refractive index 1. 39737 (1. 3974). Decomposition in water, soluble in ethanol, acetone, ethyl benzene, benzene and chloroform.
The mixture of methanol and formaldehyde was reacted with hydrogen chloride gas. The raw materials and tail gas in the production process contain hydrogen chloride, which causes serious corrosion to the equipment. At present, domestic production uses water to absorb hydrogen chloride in the tail gas to increase by-products and reduce pollution.
chloromethyl agent, mainly used in the production of anion exchange resin, also used in the production of pharmaceutical sulfadiazine.
