【発明の詳細な説明】
本発明は、式
で表わされる新規な３，3′−ベンジリデン−ビス
（４−ヒドロキシ安息香酸ベンジルエステル）に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the formula This invention relates to a novel 3,3'-benzylidene-bis(4-hydroxybenzoic acid benzyl ester) represented by:
本発明の化合物は、たとえばベンズアルデヒド
と４−ヒドロキシ安息香酸ベンジルエステルとを
適当な溶媒（トルエン、ベンゼン、クロロホル
ム、ジクロロエタンなど）に溶かし、ルイス酸や
プロトン酸などの酸触媒の存在下に反応させるこ
とにより得ることができる。 The compound of the present invention can be produced by, for example, dissolving benzaldehyde and benzyl 4-hydroxybenzoic acid ester in a suitable solvent (toluene, benzene, chloroform, dichloroethane, etc.) and reacting the solution in the presence of an acid catalyst such as a Lewis acid or a protonic acid. It can be obtained by
本発明化合物は、ゴキブリや白蟻などの衛生害
虫に対して忌避作用を有し、従つて、たとえば害
虫忌避剤として有用である。また、熱可塑性ポリ
マーに対して可塑化効率がすぐれているため柔軟
性、弾性、可塑性を増加させ、揮発性も少ないこ
とからポリマーの可塑剤としても有効である。 The compounds of the present invention have a repellent action against sanitary pests such as cockroaches and termites, and are therefore useful, for example, as pest repellents. Furthermore, since it has excellent plasticizing efficiency compared to thermoplastic polymers, it increases flexibility, elasticity, and plasticity, and because it has low volatility, it is also effective as a plasticizer for polymers.
