Methylene chloride
Molecular formula: CH2Cl2
Molecular weight: 84.93
Colorless tran***rent liquid, heavier than water and volatile. Have the similar smell of the ether and sweet, no burning, but mixes with high concentration of oxygen form explosive mixture methylene chloride., slightly soluble in water and most commonly used organic solvents miscibility, and other chlorinated solvents, ether and ethanol can be arbitrary proportion miscibility.Methylene chloride at room temperature hardly soluble in liquid ammonia, quickly dissolved in phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, formamide, cyclohexylamine, ethyl acetoacetate.Pure methylene chloride without flash point, methylene chloride and gasoline containing such as volume, solvent naphtha or toluene solvent mixtures is non-flammable, however, when the methylene chloride and acetone or methanol liquid to 10:1, mixing ratio, its mixed with flash point, vapor and air form explosive mixture, explosion limit of 6.2% ~ 6.2% (volume). methylene chloride methane chloride is the smallest, toxic toxicity was only about 0.11% of the toxicity of carbon tetrachloride.If the methylene chloride directly splash the eyes, pain and corrode action.An anesthetic effect of steam of methylene chloride.When the serious poisoning danger immediately out of contact and moved to fresh air place, some symptoms can ease or disappear, won't cause lasting damage.
Methylene chloride with dissolving ability strong and the characteristics of low toxicity, a large number of used in the manufacture of safety film, polycarbonate, the rest used for coating solvent, metal degreasing agent, smoke gas injection agent, polyurethane foaming agent, release agent, paint remover.Used as reaction medium, used in the pharmaceutical industry for the preparation of ampicillin, hydroxy benzyl penicillin and cephalothin, etc.;Also used as a solvent in film production, oil dewaxing solvent extraction solvent, aerosol propellant, organic synthesis, polyurethane foaming agent and f |
