General characters:
Colorless liquid,with characteristic odor,Relative density D4201.326,Melting point-96.7ºC,Boiling point:40.4ºC,
If it is mixed with high concentrated oxygen,the explosive mixture is formed but it is not inflammable,It is one of the low-boiling-point industrial solvents that have small itoxicity,no inflammable,It has good solubility for many resin,wax and fat,soluble in water slightly,easy soluble in other chloro solvent,ethoxyethane and ethanol.Dichloromethane can take place hydrolysis with water in certain temperature,The commercial dichloromethane often contains stabilizer in order to prevent decomposition.
Usage:
Dichloromethane has strong solubility and notoxicity,used for manufacturing safety film and orthocarbonate and use for solvent of paint,cleaner for metal, gas-fog spray agents,polyurethane foaming agent,mold-release agent,paint remover.Dichloromethane is also use in the manufacture of photographic film and has been used to remove caffeine from coffee.also approved for use as a postharvest fumigant for grains and strawberries and as a degreening agent for citrus fruit.
