Problems solved by technology
[0002] The catalyst used in the existing industrial technology for the alkylation reaction of propylene and phenol is p-hydroxybenzenesulfonic acid, and its reaction time is generally as long as 10-12 hours , the reaction time is long, and the conversion rate is only about 90%, and p-hydroxybenzenesulfonic acid cannot be reused as a catalyst, and the use efficiency is very low, which causes a certain waste of resources. Therefore, we began to look for a method that can High-efficiency catalyst for repeated use

Abstract
The invention provides a catalyst for the alkylation reaction of propylene and phenol, which comprises the following weight percentages of raw materials: 30-40% of diatomite, 15-25% of epoxy resin and 40-50% of p-hydroxybenzenesulfonic acid. After the formula raw materials are mixed, dried, processed into granules, and dried again to obtain the finished product. The catalyst of the invention is applied to the alkylation reaction of propylene and phenol, which can shorten the alkylation reaction time, increase the conversion rate and reduce the production cost.
Description
technical field [0001] The invention relates to the field of alkylation reaction of organic matter, in particular to a catalyst for alkylation reaction of propylene and phenol and a preparation method thereof. Background technique [0002] The catalyst used in the existing industrial technology for the alkylation reaction of propylene and phenol is p-hydroxybenzenesulfonic acid, and its reaction time is generally as long as 10-12 hours. The reaction time is relatively long, and the conversion rate is only about 90%. , and p-hydroxybenzenesulfonic acid cannot be reused as a catalyst, and the use efficiency is very low, which causes a certain waste of resources. Therefore, we began to look for a high-efficiency catalyst that can be reused. Contents of the invention [0003] The invention provides a catalyst for the alkylation reaction of propylene and phenol and a preparation method thereof. The use of the catalyst improves the speed of the alkylation reaction of propylen...
