Heat conducting oil cooling device for preparing pentaerythrityl tetrastearate

Abstract

The invention discloses a heat conducting oil cooling device for preparing pentaerythrityl tetrastearate and belongs to the technical field of chemical production. The heat conducting oil cooling device comprises a heat conducting oil storing barrel; the top end and the bottom end of the conducting oil storing barrel are connected with an oil discharging pipeline and an oil feeding pipeline separately; the oil discharging pipeline extends to the interior bottom of the conducting oil storing barrel; a spiral cooling pipeline is connected between the oil discharging pipeline and the oil feedingpipeline; the oil feeding pipeline is connected with a circulating oil pump; a spiral cooling water pipe sleeve wraps the outer wall of the spiral cooling pipeline; and a cooling water cylinder is arranged on the right side of the spiral cooling pipeline, circulating cooling water can be utilized to rapidly cool heat conducting oil, and a heat absorption effect generated through chemical reactionbetween acetic acid solution and ammonium bicarbonate is utilized to rapidly cool cooling water, so that the cooling effect of cooling water can be effectively ensured, stable cooling of heat conducting oil can be effectively improved, and effective control over the cooling process of cooling water is realized.

Description

technical field [0001] The invention relates to the technical field of chemical production, more specifically, to a heat-conducting oil cooling device used for the preparation of pentaerythritol stearate. Background technique [0002] Pentaerythritol stearate, referred to as PETS, alias: pentaerythritol tetrastearate, pentaerythritol stearate, it has good internal and external lubricity, can improve the thermal stability of products, and is non-toxic. The product is usually a white hard high-melting wax, soluble in solvents such as ethanol, benzene and chloroform. Pentaerythritol stearate has good thermal stability and low volatility at high temperature, good mold release and flow properties, excellent nucleating effect on partially crystalline plastics, and can be used for transparent products. The outstanding thermal stability of pentaerythritol stearate allows it to be used in the processing of such systems without fear of degradation, and it can significantly improve tr...
