Acetic anhydride toluene evaporation equipment based on acyclovir intermediate preparation

The acetic anhydride toluene evaporation equipment comprises an evaporation tank body, the bottom of the evaporation tank body is fixedly sleeved with a bottom plate, the top of the evaporation tank body is fixedly sleeved with a top plate, supporting columns are arranged at the corners of the lower surface of the bottom plate, vertical rods are vertically installed at the top ends of the supporting columns, and the top plate is fixedly sleeved with a top plate. The vertical rod movably penetrates through the bottom plate and the top plate, a buffering mechanism is arranged on the vertical rod and comprises a sleeve plate arranged at the top end of the vertical rod in a sleeving mode, and a compression spring arranged on the vertical rod in a sleeving mode is arranged between the sleeve plate and the upper surface of the top plate. The evaporation tank has the advantage of relieving vibration, and the problem that abrasion between connecting parts is accelerated due to shaking or even vibration of the evapora
