Triethyl borate storage using device

Abstract

The invention discloses a triethyl borate storage using device. The triethyl borate storage using device comprises a sealed tank. A liquid inlet pipe is arranged at the upper portion of the sealed tank, and a liquid outlet pipe is arranged at the lower portion of the sealed tank. The liquid inlet pipe and the liquid outlet pipe are provided with sealing valves. A sealed drying chamber is further arranged at the upper end of the sealed tank and internally provided with a ventilation pipe. The drying chamber is additionally arranged at the upper end of the sealed tank and internally provided with the ventilation pipe for ventilation, and when part of triethyl borate needs to be taken out to be used, the sealing valves of the liquid outlet pipe and an air inlet of the ventilation pipeline areopened, the triethyl borate flows into experiment or usage equipment from the liquid outlet pipe, at the time, part of air can enter from the ventilation pipe due to pressure intensity, the part of air flows in from the ventilation pipe, is subjected to drying and dehumidification through a drying agent in the ventilation pipe and enters the sealed tank, and the situation that the humidity and water content of part of air are large, and consequently triethyl borate hydrolysis is caused is prevented.

Description

technical field [0001] The invention relates to the production and storage of trimethyl borate, in particular to a device for storing and using triethyl borate. Background technique [0002] Triethyl borate is a colorless and transparent liquid with a slight odor and remarkable thermal stability. Its biggest feature is that it is easy to absorb moisture and easily decomposes into ethanol and boric acid when it meets water. Therefore, the storage tank of triethyl borate It is necessary to carry out drying and dehumidification to keep the tank dry; but when part of the trimethyl borate is taken out of the tank for use, due to pressure and sealing, additional gas needs to enter the tank, and this part of the gas may contain more The moisture will lead to the hydrolysis of the remaining triethyl borate, which will bring certain troubles to the storage and use of triethyl borate. Contents of the invention [0003] The object of the present invention is to provide a device for ...
