摘要
利用苯酐尾气吸收液生产反酸的传统生产工艺具有一定的不足,确立了反应—脱色一体化改造方案,并通过实验确立了相应地工艺条件。
The long-established traditional technique is deficient that using the exhaust-absorption solution of phthalic acid anhydride to produce fumaric acid, Under the present process condition, the technical method of reaction together with decoloration has been determined as well as the relevant technical condition through the experience.
