Hazard Information | Back Directory | [General Description]
A crystalline solid or a solid dissolved in a liquid. Insoluble in water and denser than water. Contact may slightly irritate skin, eyes and mucous membranes. May be slightly toxic by ingestion. Used to make other chemicals. | [Reactivity Profile]
METHYL CHLOROACETATE(96-34-4) is a halogenated ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Hazard]
Toxic by ingestion and inhalation. | [Health Hazard]
Extremely corrosive to the eyes, skin, nose, throat, and upper respiratory tract. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. | [Fire Hazard]

CLEAR COLOURLESS LIQUID | [Uses]
As solvent. | [Application]
Methyl chloroacetate (MC) is a halogenated ester mainly used as a solvent in organic synthesis or in the preparation of several compounds. Typically, MC is used in the preparation of (carboxymethyl) trimethylammonium chloride estersor in the synthesis of octakis- (carbethoxymethoxy)calix[8]arene. Additionally, methyl chloroacetate acts as an extraction solvent during the separation of neutral compounds with concentration enhancement using coupling liquid–liquid semi-microextraction with micellar electrokinetic chromatography through oncapillary decomposition. | [Preparation]
Methyl chloroacetate is prepared by esterification of chloroacetic acid with methanol. Reaction: Methanol and chloroacetic acid are uniformly mixed in a weight ratio of 0.366:1, heated with stirring, and the esterification reaction is carried out at 105-110 °C. In the reaction process, the ternary azeotrope of methyl chloroacetate, water and methanol is continuously steamed, layered through the ester separator, the separated methanol and water are returned to the reaction pot, and the separated crude ester is made of sodium carbonate. neutralize. The neutralized crude ester is firstly cut out the 130°C fraction by atmospheric distillation, and then subjected to vacuum distillation to collect the 65°C (8kPa) fraction, which is the finished product of methyl chloroacetate. The yield is about 96%. | [Synthesis Reference(s)]
