- the mixture was further heated to carry out a hydrolysis reaction at a reflux temperature for about 3 hours.
- reaction mixture was kept at 70-80 ° C and allowed to stand.
- the aqueous layer was separated (reaction separated aqueous layer), and 120 gr of warm water at 50-60 ° C was added to the oil layer and stirred for about 1 hour. Then, the mixture was allowed to stand still at the same temperature, and the aqueous layer was separated (washing aqueous layer). This operation was repeated three times. After that, free water in the oil layer was azeotropically dehydrated, 2.6 gr of activated clay was added at 70 to 80 ° C, and the mixture was decolorized and filtered.After that, 60 gr of water was added and the mixture was cooled to 25 ° C or less, and the precipitate was removed.
- reaction separation aqueous layer and the washing water ⁇ are cooled to 20 ° C or less, and the precipitate is collected by filtration, and circulated to 8.4 gr of HBP (7.8 gr in terms of 14.8, 3% yield to OPP). Received. HCA total yield 97%.
- the condensation reaction product mixture obtained in the same manner as in Example 1 was cooled to about 100 ° C, 120 gr of toluene was added, and further cooled to about 30 ° C.
- the reaction mixture was gradually poured into a reactor equipped with a reflux condenser equipped with 240 gr of water and 600 gr of toluene under stirring, and then heated to carry out a hydrolysis reaction at a reflux temperature for about 3 hours. Was performed. Thereafter, the reaction mixture was washed under pressure (4 m water column) at 80 to 90 ° C three times with 150 ml of acidic hydrochloric acid 3 times, and twice with 1 O of water 15 Om, and then cooled under reflux.
- the vessel was switched to an outflow cooler, heated under normal pressure and subjected to azeotropic dehydration to carry out a closing reaction.
- HBP was converted to HC A, and the temperature of the content mixture reached about 115 ° C. By the way, there was no longer any azeotropic outflow of water.
- the content mixture was decolorized and filtered with 2.6 g of activated clay, cooled to about 5 ° C., and the precipitate was separated by filtration, washed with toluene, and dried to obtain 251.1 gr of a white powder. Melting point 118 ° C. Elemental analysis and infrared spectrum analysis confirmed that this was HCA. purity 99.9%. OPP, Zn, C1 and Na contents were all less than 1 ppm.
- the condensation reaction mixture obtained in the same manner as in Example 1 was cooled to about 100 ° C. and poured into 1,700 g of an 8.5% aqueous sodium hydroxide solution with stirring. During this time, the injection mixture rose from 25 ° C to 70 ° C. After stirring for about 1 hour, the pH was adjusted to 4.5 with dilute sulfuric acid, 15 g of activated carbon was added, and the mixture was stirred at 50 to 60 for 0.5 hour, and then filtered. The filtrate was acidified to pH 1.5 with dilute sulfuric acid at 25 ° C or lower, and the precipitate was filtered and washed with water to obtain white crystalline granular HBP.
- the condensation reaction mixture obtained in the same manner as in Example 1 was further kept under a reduced pressure of about 1 mmHg at about 210 ° C. under stirring to remove hydrogen chloride gas and phosphorus trichloride. After cooling to about 100 ° C, 220 gr of chlorobenzene was added and kept at about 70 ° C. To this, water (21.6 gr, 1.2 mol) was added in about 6 hours, and then the temperature was gradually raised and reacted at the reflux temperature for 9 to 10 hours. After the generation of hydrogen chloride gas stopped, the reaction mixture was reduced to about 100 after the reaction was completed.
- the compound represented by the general formula (3) itself is used as a stabilizer and a flame retardant for organic low-molecular and high-molecular compounds, and also as an auxiliary agent for improving the quality and yield in the production thereof. Have been. It is also an important compound as a raw material for the production of many more stabilizers, flame retardants and flame-retardant polymer compounds.
- the compound represented by the general formula (2) is important as a raw material for producing the compound represented by the general formula (3), and further as a raw material for producing a stabilizer and a flame retardant for organic low-molecular and high-molecular compounds. . Both compounds are expected to further expand their applications in the future.
- ADVANTAGE OF THE INVENTION According to the present invention, it is easy to operate without requiring special chemicals and equipment of high quality, high purity, high quality, and especially the content of raw materials and by-product organic compounds and inorganic compounds is extremely small. Can be produced in high yield.
