Chemically synthesized aromatic hydrocarbon heat transfer fluid and its preparation method

Abstract

The invention relates to a chemically synthesized aromatic hydrocarbon heat transfer liquid and a preparation method thereof. The invention belongs to the field of chemical heat transfer oil preparation. The heat transfer liquid is prepared by adding a functional auxiliary agent in a polycyclic aromatic hydrocarbon mixture. The functional auxiliary agent is prepared from the raw materials of, by mass: 30% of a high-temperature antioxidant alkyldiphenylamine, 10% of an anti-aging agent 2,6-di-tert-butyl-phenol, 30% of a detergent sulfurized alkylphenol calcium, 20% of base synthetic calcium sulfonate in the detergent, 3% of KX-ZJ-01 high-temperature decoking agent, and 7% of KX-ZS-03 hydrogenation scale inhibitor. The heat transfer liquid has wide application temperature, and can be used under a temperature ranged from -20 DEG C to 330 DEG C, which exceeds a national standard. The heat transfer liquid is safe and environment-friendly, and has good heat transfer performance and long service life.

Description

technical field [0001] The invention relates to a chemically synthesized aromatic hydrocarbon 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 thermal conductivity, 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 reactions, etc. However, most of the chemically synthesized aromatic heat transfer fluids on the market currently use a temperature range It is relatively narrow and cannot be used for wide changes in temperature, which will lead to unstable p...
