Abstract

본 발명은 폴리인산의 새로운 제조방법에 관한 것이다.The present invention relates to a new process for producing polyphosphoric acid.

본 발명의 가열/진공 시스템에 의한 인산축합반응은 온도 및 압력 조건에 의존하며, 이 조건들을 조절함으로써 원하는 함량의 폴리인산을 쉽게 경제적으로 제조할 수 있는 새로운 방법을 세공한다.The phosphoric acid condensation reaction by the heating / vacuum system of the present invention is dependent on temperature and pressure conditions, and by adjusting these conditions, a new method for easily and economically preparing polyphosphoric acid of a desired content is poised.
