Methylamine hydrochloride
also known as methylamine hydrochloride, is a colorless tabular crystal. Methylamine hydrochloride is used to make medicine and dyes. The preparation of methylamine hydrochloride is obtained by the interaction of methylamine and hydrochloric acid.
Use:
it is used as analytical reagent and also for organic synthesis. Production method: 1 Add chemically pure hydrochloric acid to the methylamine solution under cooling, adjust it to pH = 2 ~ 3, then decolorize, filter and concentrate under reduced pressure, and then adjust phchemicalbook = 2 ~ 3, cool and filter out crystals, which is the finished product. The reaction formula is: classification of toxic substances, toxicity classification, acute toxicity, oral - rat ld50:1600 mg / kg; Intraperitoneal mouse ld50:2160 mg / kg flammability hazard characteristics Flammability; The fire site decomposes toxic hydrogen chloride, and the storage and transportation characteristics of nitrogen oxide gas. The warehouse is low temperature, ventilated and dry; fire prevention; Store fire extinguishing agent water, carbon dioxide, dry powder and sand separately from oxidant and strong acid
Physical properties: white crystalline powder, melting point 228-233 ° C, boiling point 225-230 º C (15mmhg).
Chemical properties: very soluble in water, 20% aqueous solution ph=4.0-4.7, insoluble in ethanol, insoluble in ether, ethyl acetate, chloroform and acetone, easily deliquescent.
Quality index: ≥ 99%
Grade: CP
Application: it is used in medicine, pesticide, fuel and other basic raw materials of organic synthesis and oil fields
Packaging: 25kg/ woven bag, lined with PE film bag, 25kg cardboard barrel can also be packaged according to customer needs
