【Example】
Hereinafter, specific examples will be described, but the present invention is not limited to the following examples.
(Example 1)
In a conical beaker, 140 g of toluene and 30 g of 1,4-bis ( 1-hydroxy-1-methylethyl ) benzene (p-DIOL, manufactured by Mitsui Petrochemical Industries, Ltd.) are added, and then 250 g of 35% hydrochloric acid water is added. The mixture was further stirred at 20 ° C. with a magnetic stirrer for 90 minutes. At this time, both the organic phase and the aqueous phase changed to colorless and transparent. Thereafter, the organic phase and the aqueous phase were separated, and hydrogen chloride gas was bubbled through the organic phase at 20 ° C. for 90 minutes while being stirred with a magnetic stirrer. Then, nitrogen gas was bubbled for 45 minutes for dehydrochlorination treatment. 1H-NMR of p-DCC (crude) was obtained by evaporating the volatile components of the sample solution of the obtained toluene solution of 1,4-bis ( 1-chloro-1-methylethyl ) benzene (p-DCC). When the spectrum was measured, it was 99.5% purity. The obtained p-DCC solution is of the same high quality as p-DCC obtained by crystallizing and drying the organic phase instead of contacting with hydrogen chloride gas, and is sufficiently used as an initiator for cationic polymerization. I could do it.
(Example 2)
Example 1 was repeated under the same conditions except that the amount of 35% hydrochloric acid used was 125 g and the reaction of contacting with hydrogen chloride gas was performed at 5 ° C. Got. The obtained p-DCC solution was of the same high quality as p-DCC obtained by crystallizing and drying the organic layer, and was sufficiently usable as an initiator for cationic polymerization.
(Comparative Example 1)
The p-DCC purity before introducing hydrogen chloride gas in Example 1 was 98.0% as measured by 1 H-NMR spectrum after removing volatile components.
(Comparative Example 2)
The p-DCC purity of Example 2 before the introduction of hydrogen chloride gas was 97.0% as measured by 1 H-NMR spectrum after removing volatile components.
