Paragraph 0054; 0055, (2016/11/28)
The invention discloses a double-phenolic compound antioxidant clean production process and application. The clean production method comprises: in a solid acid catalyst, and in order to aliphatic aldehyde and dialkyl substituted phenol as raw material, the raw material and the catalyst is placed in a closed environment reaction, and the reaction of the reaction product after the end of filter heat, that is, to obtain the target product, which can be used for preparing lubricating oil composition or as a plastic, rubber, such as anti-aging agent. Antioxidant bisphenol compounds of this invention for the production of simple operation, mild conditions, such as the sources of the raw materials and catalyst, is cheap and easy to obtain, the reaction cycle is short, it is easy to control, process with high safety, low energy consumption in the producing process, high yield, high purity of the product, in the reaction process does not need to add water, organic solvent, surface active agent, there is no need to wash the product later, will not produce waste water, can greatly control and reducing pollutant emissions, is a safe and energy-saving, environmental protection art.

Paragraph 0050; 0051, (2017/03/08)
The invention discloses a mixed alkali catalyst based on double-phenol method for preparing an antioxidant and application. The preparation method comprises: the two alkyl substituted phenol and aldehyde compound is placed in the closed and in the reactor and in a mixed alkali catalyst can choose to add or not to add the presence of an organic solvent of the reaction is carried out under the condition of, and in the after the reaction is finished after processing the obtained compound antioxidant product double phenol apperception, the anti-oxidant product can be used for preparing the lubricating oil composition, composition or burns the oil line as plastic, rubber, such as anti-aging agent. Antioxidant bisphenol compounds of this invention for the production of simple operation, mild conditions, such as the sources of raw materials and catalyst of extensive and is cheap and easy to obtain, the reaction cycle is short, it is easy to control, process with high safety, low energy consumption in the producing process, the yield of the product and high purity, and can effectively control and reducing pollutant emissions, is a safe and energy-saving, environmental protection art.
