毒性和生态

毒理学数据: 1、刺激性：兔子经皮：500mg 轻度刺激。 兔子经眼：50mg 轻度刺激。 2、急性毒性：大鼠经口LD50：12565mg/kg；兔子经皮LD50：11890mg/kg 3、属微毒类。可经皮吸收，对皮肤黏膜刺激小。与乙二醇相似对中枢神经系统有抑制作用。能引起肾脏病理改变及尿路结石。人一次口服致死量估计为1mL/kg。服用二甘醇后约24小时出现恶心、呕吐、腹痛、腹泻等肠胃道症状。致死者随之出现头痛、肾区疼痛、一时性多尿然后少尿、嗜睡、面部轻度浮肿等。无尿发生后2～7日内昏迷而死。故本品应禁作药用，避免长期与皮肤接触。 生态学数据: 对水体有轻微的危害。 CHEMICAL IDENTIFICATION RTECS NUMBER : ID5950000 CHEMICAL NAME : Diethylene glycol CAS REGISTRY NUMBER : 111-46-6 BEILSTEIN REFERENCE NO. : 0969209 LAST UPDATED : 199712 DATA ITEMS CITED : 56 MOLECULAR FORMULA : C4-H10-O3 MOLECULAR WEIGHT : 106.14 WISWESSER LINE NOTATION : Q2O2Q HEALTH HAZARD DATA ACUTE TOXICITY DATA TYPE OF TEST : Standard Draize test ROUTE OF EXPOSURE : Administration onto the skin SPECIES OBSERVED : Human REFERENCE : 85DKA8 "Cutaneous Toxicity, Proceedings of the 3rd Conference, 1976," Drill, V.A., and P.

制备

1.一缩二乙二醇是环氧乙烷制乙醇时的副产品。 工艺流程： 用直接水合法 将环氧乙烷与水按1：8混合送入混合反应器，在150℃MPa下，反应40-60min,生成脱水塔进一步脱水；塔底的乙二醇混合液送入乙二醇塔，塔顶可得99.8%以上的乙二醇。塔底液送入一缩精馏塔，在塔顶温度135-140℃,压力4.0KPa下，从塔顶得到一缩二乙二醇。继续分离，可得二缩三乙二醇、三缩四乙二醇。 精制方法：所含杂质有水、乙二醇、三甘醇等。可用减压蒸馏后分步结晶的方法精制。取二甘醇1650mL进行减压分馏，弃去480mL初馏分，收集1000mL中间馏分进行分步结晶，可得700mL二甘醇。 2. 与酸酐作用时生成酯，与烷基硫酸酯或卤代烃作用生成醚。 3. 合成：由环氧乙烷与乙二醇作用而制得。也是环氧乙烷水合制乙二醇时的副产品。
