MUTHMANNS LIQUID - Preparation Method
Open Data Verified Data
purified acetylene was directly introduced into a reactor in which bromine and water were put in advance, and the pressure was controlled. The reaction was carried out at 9613 to 4.9033kPa and a reaction temperature of <50 ° C., and then the reaction was washed with dilute alkali solution, and the upper alkali solution was removed and then washed with water to obtain a finished product.

| Use | used in the synthesis of quaternary ammonium compounds, used as pharmaceutical and dye intermediates, it is also a catalyst for the oxidation of p-xylene to terephthalic acid This product is used as an intermediate for quaternary amine compounds, pharmaceuticals and dyes, and is also used for the preparation of chemical fiber promoters, initiators, flame retardants, refrigerants, fire extinguishing agent, fumigation disinfectant, etc. used for separation of ore, determination of ore specific gravity and refractive index, etc. used as plastic foaming, polyester initiator, also used in chemical fiber catalysis and flame retardant, solvent for microscope, solvent for grease and wax, and instrument solution shall be used to separate minerals according to specific gravity. |
| production method | is obtained by addition of acetylene and bromine. Bromine was added to a glass-lined reaction pan, and a small amount of water was added to close the liquid surface of bromine. Then, acetylene gas was slowly introduced from the liquid, and the aeration reaction was maintained at 58-62 ° C. Under the conditions of 0.02-0.05MPa for 5-7 hours, and the reaction was stopped when the reaction solution became yellow. The reaction solution was washed with dilute sodium carbonate solution, then washed with clear water until neutral, and the washing water was separated and purified to obtain the finished tetrabromoethane. Raw material consumption quota: bromine 1110kg/t, calcium carbide 1940kg/t. |
