Molecular formula : C2H5ClO
MW : 80.51
CAS No. CAS-30-2
nature : colorless and transparent liquid. Has ° C melting point, boiling point, 59 ° C (59.1 ° C) and relative density of 1.07 (20 / 4 ° C), 1.39737 refractive index, a flash point of 15 ° C. A decomposition of water, soluble in ethanol, acetone, ethyl benzene, benzene and chloroform. There irritating odor, easy mobility, volatile. With tear gas.
Preparation : calcium chloride in the presence of hydrogen chloride gas into methanol and-a mixture of formaldehyde, slightly above room temperature occurred under the conditions Aldol derived and the addition reaction. Kettle happened to the hydrogen chloride into industrial hydrochloric acid (HCl product may exhaust), 70 ° C 71/92 sulfate (92%), the hydrogen chloride gas into Qualcomm with methanol, formaldehyde solution of the reactor were chlorinated. Temperature control in 40 ° C, methanol (98%) and formaldehyde (37%) than the weight of 1:2.39. When the reactor hydrogen chloride absorption capacity after completion of the chlorination. Still then layered 1h, its upper floors of chlorine ether synthesis and the lower layer of acid, chlorine to the final with acid dimethyl ether layer separation. Chlorine ether yield of 78%. The consumption of raw materials fixed : methanol (98%) 0.5t / t, formaldehyde (37%) 1.2 t / t, sulfuric acid (92%) by 3.5t / t, hydrochloric acid (33%) 2.6t / t.
purposes : lively organic intermediates. Chloromethyl agent, mainly for the production of anion exchange resin, used in the production of sulfadiazine drugs.
