Reference of 599-67-7, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 599-67-7, name is 1,1-Diphenylethanol. This compound has unique chemical properties. The synthetic route is as follows.
Into a 1-liter reaction flask were introduced 200.23 g of the crude 1,1-diphenylethanol obtained above, 400 ml of toluene, and 1 g of p-toluenesulfonic acid (PTSA). Azeotropic dehydration was conducted for 2 hours with toluene refluxing (94-116 C.). The resulting reaction mixture was cooled, washed with water and then with 2% soda ash solution, dried with magnesium sulfate, and concentrated to obtain 190.09 g of crude 1,1-diphenylethylene (4a; R1,R2 =H). This crude 1,1-diphenylethylene (4a) was distilled with a Claisen flask equipped with a vigreux (b.p., 103 C./1 mmHg), giving 174.06 g of 1,1-diphenylethylene (4a). The theoretical yield based on the benzophenone was 96.5%.
According to the analysis of related databases, 599-67-7, the application of this compound in the production field has become more and more popular.
