酞酐即邻苯二甲酸酐,分子式为C_6H_4(CO)_2O。酞酐是由萘在五氧化二矾催化下经氧化而生成的,是合成涤纶的原料。酞酐属低毒类,有一种特殊气味,溶于酒精,极微溶于水,遇潮湿可水解成酞酸。当空气浓度为30mg/m~3时,可产生上呼吸道刺激症状,皮肤接触后可致湿疹,荨麻疹。我院曾收治一例酞酐致反复哮喘发作的患者。现报告如下。
Phthalic anhydride phthalic anhydride, molecular formula C_6H_4 (CO) _2O. Phthalic anhydride by naphthalene in the pentoxide oxidation catalyzed by the generated, is the synthesis of polyester raw materials. Phthalic anhydride is a low-toxic, a special smell, soluble in alcohol, very slightly soluble in water, in case of moisture can be hydrolyzed into phthalic acid. When the air concentration of 30mg / m ~ 3, can produce upper respiratory tract irritation, skin contact can cause eczema, urticaria. Our hospital had admitted a case of repeated attacks of phthalocyanine in patients with asthma. The report is as follows.
