Abstract
Description
(式中、R1、R2は各々独立に水素原子又はメチル基を表し、nは1~5の数を表す。)
Mx Mgy Alz CO3(OH)xp+2y+3z-2・nH2O (II)
(式中、Mはアルカリ金属または亜鉛を、xは0~6の数を、yは0~6の数、zは0.1~4の数を、pはMの価数を、nは0~100の結晶水の数を表す。)
ジヒドロキシ化合物(表1記載)に触媒として塩化マグネシウムを9.52g(0.01mol)加え、オキシ塩化リンをジヒドロキシ化合物の6倍モル添加して80~100℃で3時間反応させた。余剰のオキシ塩化リンを減圧留去したのち、フェノール化合物(表1記載)を添加し、120~140℃で7時間反応させた。得られた粗生成物をトルエンに溶かし、酸あるいは塩基を含む水溶液で洗浄したのち、脱水・脱溶媒することでリン酸エステル化合物を得た。得られた化合物はIR分析、NMR分析により下記式(III)で表されるリン酸エステル化合物であることを確認し、液体クロマトグラフにより下記式(III)においてn=1に該当する化合物の純度を測定した。
得られたリン酸エステル化合物100質量部を120℃で1時間撹拌して溶融状態としたのち、表1記載の種晶添加温度まで冷却し、表1記載の配合量で種晶を添加して攪拌した。撹拌できなくなるまでの時間を固体化時間として評価した。固体化時間は短いほど工業的に優れた固体化条件であることを意味するが、冷却のためのコストなどもあるため120分を最長測定時間として評価した。結果を表1に示す。
種晶は、カラムで前記式(III)のn=1に該当する化合物を精製して20℃で24時間冷却して得られた固形物を粉砕したものを用いた。
