补充资料:聚乙二醇
聚乙二醇又称聚乙二醇醚,简称PEG,结构式为HO(CH2CH2O)nH,根据分子量大小不同,可从无色透明粘稠液体(分子量200~700)到白色脂状半固体(分子量1000~2000)直至坚硬的蜡状固体(分子量3000~20000),相对密度(20℃/20 ℃)1.12~1.15。作为增韧利用的聚乙二醇主要是分子量200~600的室温下为无色透明的粘性液体,无味。易溶于水,溶于甲醇、乙醇、丙酮、醋酸乙酯、苯、甲苯、二氯乙烷、三氯乙烯等.不溶于脂肪烃。对酚类溶解能力强,当皮肤上附有苯酚、甲酚时,可用分子量约400的聚乙二醇除去。与硝酸纤维素、松香、酪阮可以混合.但对一般的合成树脂不溶解,对橡胶也不溶胀。吸湿性大。聚乙二醇在正常条件下是很稳定的,但在120 ℃或更高温度下能与空气中的氧发生氧化作用。加热至300 C产生断裂或热裂解。聚乙二醇不挥发.闪点高,对金屑无腐蚀性。无毒,对眼睛和皮肤无明显刺激,LD5033000~43000mg/kg。
用作环氧树脂和聚乙烯醇的增韧剂。
贮存于干燥的库房内,远离火源。
