To prepare 4,4 '- [ (1,1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) bis (benzene-4,1-diyloxy) ] dibenzoic acid, the method is as follows:
First take an appropriate amount of 1,1,3,3-hexafluoroisopropyl-2,2-diyl-related starting materials, and place them in a suitable reaction vessel with compounds containing benzene-4,1-diyloxy. This container should be clean and dry to prevent impurities from disturbing it.
Next, add an appropriate amount of catalyst and solvent. The catalyst can promote the rate of the reaction, and the solvent will assist in the mixing of the raw materials and the progress of the reaction. The catalyst and solvent used should be carefully selected according to the characteristics and requirements of the reaction.
Then, strictly control the temperature and time of the reaction. Heat up to a specific temperature range and maintain it for a certain period of time to fully react the raw materials. Too high or too low temperature, too short or too long time may affect the yield and purity of the product.
After the reaction is completed, the resulting mixture is treated by separation and purification. Or by filtration, extraction, distillation, recrystallization, etc. to remove impurities to obtain pure 4,4 '- [ (1,1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) bis (benzene-4,1-diyloxy) ] dibenzoic acid.
During the whole process, the operation should be fine, and all links need to be carefully controlled to obtain satisfactory results.

Today there is a product called 4,4 '- [ (1,1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) bis (benzene-4,1-diyloxy) ] dibenzoic acid. However, it is difficult to determine how the price trend of this product is in the market.
Looking at the market, the price of a product often depends on various reasons. First, it is related to supply and demand. If this 4,4' - [ (1,1,1,3,3,3-hexafluoroisopropyl-2,2-diyl) bis (benzene-4,1-diyloxy) ] dibenzoic acid is needed in large numbers and the supply is limited, the price will increase; if the supply exceeds the demand, the price will decrease.
Second, it is related to the manufacturing cost. If the raw materials required for its manufacture are rare, or the manufacturing process is complicated and labor-intensive, the cost will be high and the price will also be high; on the contrary, if the raw materials are easy to obtain and the manufacturing process is simple, the cost will drop and the price will also drop.
