Abstract

The invention discloses a cleaner production method and a use of a bisphenol compound anti-oxidant. The cleaner production method comprises that fatty aldehyde and dialkyl-substituted phenol as raw materials undergo a reaction in the presence of a solid acid as a catalyst in an enclosed environment and the reaction product is subjected to hot filtration so that a desired product is obtained. The desired product can be used for preparation of a lubricating oil composition or can be used as an antiager of plastic and rubber. The production method of the bisphenol compound anti-oxidant has the advantages of simple processes, mild conditions, use of a catalyst and raw materials with a wide source, a cheap price and easy availability, short reaction period, control convenience, high process safety, low energy consumption in production, high yield, high product purity, no use of moisture, an organic solvent and a surfactant in the reaction, no use of a water washing product in the later period, no production of waste water and control and reduction of pollutant discharge. The production method is a safe, energy saving and eco-friendly novel technology.

Description

technical field

[0001] The invention relates to an antioxidant product, in particular to a clean production method and application of a bisphenol compound antioxidant. Background technique

[0002] Lubricating oil refers to liquid or semi-solid lubricants used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, and sealing. Lubricating oil is composed of base oil and additives. Base oil is the main component of lubricating oil and determines the basic performance of lubricating oil. Additives can make up for and improve the performance of base oil. On the one hand, additives can impart properties or performances that the base oil itself does not have, such as anti-foaming, demulsification, etc.; on the other hand, it can also improve the original properties or properties of the base oil, such as anti-oxidation, anti-wear, anti-rust,...
