Product Description

N-methyl-3-pyrrolidinol cas number 13220-33-2, colorless transparent liquid with irritating,easily soluble in water, soluble in ethanol, ether, benzene, Mainly used in the pharmaceutical industry. The transport storage method of N-methyl-3-pyrrolidinol 13220-33-2 can refer to N-methyl-2-pyrrolidone. The manufacturing process is basically as following put the butyrol and acetic acid into the reaction reactor, stirring heated to about 100 ℃, through the dry hydrogen chloride gas, reacted 30 hours between 90 ~ 110 ℃ , when the exhaust began to appear a lot of hydrogen chloride , Check the end of the reaction, stop enter hydrogen chloride. After cooling, the material was washed with saturated sodium carbonate solution and distilled under reduced pressure. The fraction was collected at 120-135 ° C (12.6 to 13.3 kPa) to obtain 1,4-dichloro-2-butanol, And then put it with methylamine aqueous solution into the ring reactor, sealed heated to 120 ℃, stirring reaction with lOh. Cooling, adding solid sodium hydroxide, filtering the precipitated inorganic salt. Separate the oil layer for vacuum distillation, collecting 76 ~ 85 ℃ (2.lkPa) fractions, it is finished product N-methyl-3-pyrrolidinol cas number 13220-33-2. The aqueous layer was extracted with benzene to give a portion of 1-methyl-3-pyrrolidinol.
