Embodiment 1

[0013] The dichloromethane solution of sulbactam methyl chloride requires vacuum distillation of dichloromethane to extract sulbactam methyl chloride. The height of the receiving tube of the volatile solvent vacuum distillation system is 8m, the inner diameter of the lower port is 15mm, and the inner diameter of the upper port is 100mm. Pump 1000L intermediate solution to the evaporating tank, close the remote control valve, turn on the vacuum to -0.1Mpa, slowly heat the evaporating tank until the solvent distills out, so that the solvent is filled with the receiving tube, and the liquid level rises slowly when it approaches the upper end of the glass cup Open the remote control valve to let the dichloromethane flow out slowly for storage. With the increase or decrease of the distillate volume, slowly adjust the remote control valve to increase or decrease the outflow of dichloromethane, and always keep the liquid level above and below the glass sight cup between the ends unti...

Abstract

The invention relates to a volatile solvent reduced-pressure distillation system which comprises an evaporation tank 1, a condenser 2, a vacuum pump 3, a vapor-liquid separator 4, a glass cup 5 and a receiving pipe 6, wherein the receiving pipe has certain vertical height, the distilled solvent can directly flow out from the receiving pipe under vacuum conditions and a liquid column at certain height can be kept in the receiving pipe, and the distilled solvent can continuously flow to atmospheric environment through the receiving pipe due to differential pressure of the liquid column while the vacuum degree of the distillation system is not affected. The loss of the solvent can be efficiently reduced, the environment pollution can be decreased, and the distillation time can be shortened.

Description

technical field [0001] The invention relates to a solvent vacuum distillation system, in particular to a volatile solvent vacuum distillation system. Background technique [0002] Volatile solvents are generally distilled at atmospheric pressure, but in the process of biochemical and chemical synthesis, vacuum distillation is used to extract solutes. The existing vacuum distillation system generally includes an evaporation tank, a condenser, a vacuum pump, a receiving tank, and vacuum conditions. The solvent distilled down flows to the receiving tank for accumulation and collection, and then released for storage. The receiving tank generally adopts a cylindrical structure with a certain cross-sectional area. Volatilization occurs when exposed to vacuum conditions, and this volatilization is likely to cause solvent loss, environmental pollution, and vacuum degree attenuation. Slender receiving tanks are often used to reduce volatilization, but the reduced cross-section of th...
