Advanced chemical synthesis of dibenzyltoluene heat transfer liquid and preparation method thereof

Abstract

The invention relates to advanced chemically synthesized dibenzyltoluene heat transfer fluid and a preparation method thereof. The method belongs to the field of chemical engineering heat transfer oil. The method is characterized in that the fluid is prepared by adding a functional auxiliary agent into dibenzyltoluene. The functional auxiliary agent is prepared from the raw materials of, by mass: 30% of a high-temperature antioxidant alkyldiphenylamine, 30% of a detergent sulfurized alkylphenol calcium, 30% of base synthetic calcium sulfonate in the detergent, 4% of a KX-ZJ-01 high-temperature scorch resisting agent, and 6% of a KX-ZS-03 hydrogenation inhibitor. The heat transfer fluid has excellent high-temperature resistance, and can resist temperature up to 400 DEG C. The material is a currently best heat carrier which is better than that of a national standard. The material is safe and environment-friendly, and has the advantages of good heat transferring performance and long service life.

Description

technical field [0001] The invention relates to an advanced chemically synthesized dibenzyltoluene heat transfer fluid and a preparation method thereof, belonging to the field of chemical heat transfer oil preparation. Background technique [0002] At present, in the normal production process in the chemical industry, it is often necessary to heat the reactor, etc., so the use of heat transfer oil has become inevitable in the chemical industry. Of course, not only in the chemical industry, the use of heat transfer oil is becoming wider and wider. It It has excellent heat conduction performance, and at the same time, through the conduction of heat transfer oil, the objects that need to receive heat are heated evenly, ensuring the normal progress of the reaction, etc. However, the high temperature resistance of the current conduction fluids on the market is not good. When the temperature is high, the performance of the heat transfer oil will change. When the temperature is too...

[0002] At present, in the normal production process in the chemical industry, it is often necessary to heat the reactor, etc., so the use of heat transfer oil has become inevitable in the chemical industry. Of course, not only in the chemical industry, the use of heat transfer oil is becoming wider and wider. It It has excellent heat conduction performance, and at the same time, through the conduction of heat transfer oil, the objects that need to receive heat are heated evenly, ensuring the normal progress of the reaction, etc. However, the high temperature resistance of the current conduction fluids on the market is not good. When the temperature is high, the performance of the heat transfer oil will change. When the temperature is too high, the performance of the heat transfer oil will be unstable, the service life will be reduced, and the heat conduction effect will be poor.
