반응성 단량체로서의 고순도 로진-말레산 부가물의 합성

Synthesis of Highly Purified Rosin-Maleic Anhydride Adducts as Reactive Monomer

초록

로진과 말레산무수물로부터 rosin-maleic anhydride adduct(RMA)를 합성하였다. 중합반응의 단량체로서 이용하기 위한 고순도의 RMA의 합성에는 정제공정을 수반하는 용융합성법과 정제공정이 불필요한 용액합성법을 이용하였다. 용액합성법에서 합성한 RMA의 수율이 용융합성업보다 높았다. 용융합성법의 최고수율은 40%였으나 사염화탄소 및 아세트산을 반응용제로하는 용액합성법에서 얻은 생성물의 수율과 순도를 검토한 결과 비교적 고순도의 RMA를 얻을 수 있었고, 수율은 사염화탄소 용제법의 경우 48%(이론수율 87.6%), 아세트산 용제법의 경우 51% (이론수율 94% )였다.

Rosin-maleic anhydride adduct(RMA) was synthesized from rosin and maleic anhydride. Highly purified RMA for the application of polymerization monomer was synthesized by means of two methods; the melt reaction followed by further purification and the solution reaction. As a result of this study, the solution reaction was better than the melt reaction for obtaining higher yield of RMA. Maximum yield of RMA obtained by the melt reaction was only 40%. But the yield of RMA obtained by the reaction in carbon tetrachloride solution was 48%(theoretical yield 87.6% ) and that obtained by the reaction in acetic acid solution was 51.5% (theoretical yield 94% ) respectively.
