Paragraph 0015-0019, (2020/04/29)
The invention discloses propamocarb hydrochloride prepared from the following raw materials in parts by weight: 600 to 700 parts of propamocarb raw medicine; 300 to 500 parts of hydrochloric acid; 10to 20 parts of an auxiliary agent; and 100 to 150 parts of water. The invention relates to a preparation method of propamocarb hydrochloride. The preparation method comprises the following steps: respectively adding a propamocarb raw medicine, hydrochloric acid, the auxiliary agent and water into four storage tanks; starting freezing, stirring at the temperature of 23 to 28 DEG C; stirring while starting four delivery pumps, feeding the propamocarb raw medicine, hydrochloric acid, the auxiliary agent and water in the storage tanks into a micro-reactor, adjusting the pH value to 5-7, performingheat preservation reaction for 3-6 hours, starting vacuum decompression dehydration after heat preservation is finished, controlling the vacuum degree in the micro-reactor to be 0.098 MPa and the temperature to be less than or equal to 110 DEG C, and discharging after dehydration is finished. According to the preparation method, propamocarb hydrochloride is prepared by taking water as a solvent,the preparation method is environment-friendly and simple in process, and an obtained propamocarb hydrochloride water aqua has a relatively good prevention and treatment effect on cauliflower downy mildew.

Paragraph 0022; 0028-0033, (2018/07/30)
The invention discloses a propamocarb acid salt synthetic formulation, including chloromethane acid is propyl, N, N - dimethyl - 1, 3 - propylene diamine and water. This invention one is: does not add the hydrolyzed, also reduces the hydrolysis rate of the propyl chloroformate is, the yield from 95% increased to 98% or more; the second is: improving the production efficiency, reduced energy consumption, shortens the reaction time.
