Methylene Chloride for supply now with a cheap prcie

Combustion (decomposition) Methylene Chloride products: carbon monoxide, carbon dioxide, hydrogen chloride, phosgene. Content analysis Dichloromethane can be separated by dibutyl phthalate (DBP), then detected by GC with TCD, and compared and quantified with standard dichloromethane. Reagents: carrier gas, helium (>99.5%); carrier is white diatomaceous earth 6201 (40-60 mesh) or equivalent; stationary phase, DBP (in ether); standard sample, chromatographic pure dichloromethane; instrument, gas chromatograph with TCD; column, 3m×3~4mm (inner diameter) stainless steel column. Conditions: stationary phase, 20%: DBP/6021 vaporization temperature, 100℃; detection temperature, 100℃; carrier gas flow, 70ml/min, column temperature 70℃; TCD bridge current, 200mA~ injection volume, <20μl. The retention time (R) of other chlorinated solvents related to dichloromethane is: 0.15 for methyl chloride; 0.34 for ethyl chloride; 0.59 for 1,1-dichloroethylene; 0.85 for propylene chloride; 1.86 for carbon tetrachloride; 2.47 for chloroform. Calculation: Toxicity ADI is not specified (limited by process requirements, and the residual amount in the processed product should be minimized; FAO/WHO. 1998). Chemical properties: Colorless, transparent, volatile liquid. It has a pungent odor similar to ether. Methylene Chloride is soluble in about 50 times water, soluble in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, ethyl acetoacetate, and cyclohexylamine.

Methylene Chloride is miscible with other chlorinated hydrocarbon solvents, such as ethanol, ether, and N,N-dimethylformamide. Uses: It is a non-flammable low-boiling solvent used as a solvent in the production of cellulose acetate film, aerosols, antibiotics, and vitamins. It is also used as an extractant and metal cleaning agent. Uses: Dichloromethane is the raw material for the production of fungicides myclobutanil and imidaclobutanil, and is also a good solvent. Uses: Extraction solvent. For example, it is used to extract caffeine from coffee beans. It is also used as an extraction solvent for hops, spice oil resins, etc. It is a pigment diluent. Uses: In addition to being used in organic synthesis, this product is also widely used as a solvent for cellulose acetate film, triacetate cellulose spinning, petroleum dewaxing, aerosols, and the production of antibiotics, vitamins, and steroids, as well as a metal surface paint cleaning, degreasing, and demolding agent. In addition, it is also used for grain fumigation and refrigeration of low-pressure refrigerators and air-conditioning units. It is used as an auxiliary foaming agent in the production of polyether urethane foam plastics, and as a foaming agent for extruded polysulfone foam plastics.
