蒽醌制浆化学

PULPING CHEMISTRY OF ANTHRAQUINONE

对蒽醌在制浆过程中的化学作用机理作了说明,指出其在与木素亚甲基醌起作用的是蒽醌酮,并且在与木材的反应中,有很大的一部分是损失了,而残留于蒸煮液中的只是一小部分,故它不是周而复始起作用的催化剂。

In this paper, the chemical mechanism of anthraquinone pulping wss demonstrated. It is shown that anthranolone is responsible for the reaction of AQ on the quinone methide intermediates from lign-in. It is known that most of AQ lost their reactivity after cooking and only a small amount of AQ still remained in black liqour. Thus AQ is not a catalyst that can perform a function recirculated.
