Section8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Control parameters
Components with workplace control parameters
Exposure controls
Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and
at the end of workday.
Personal protective equipment
Eye/face protection
Face shield and safety glasses Use equipment for eye protection tested and approved under
appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique
(without touching glove's outer surface) to avoid skin contact with this product. Dispose of
contaminated gloves after use in accordance with applicable laws and good laboratory practices.
Wash and dry hands.
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and
the standard EN 374 derived from it.
Body Protection
Complete suit protecting against chemicals, The type of protective equipment must be selected
according to the concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator
with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup
to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
respirator. Use respirators and components tested and approved under appropriate government
standards such as NIOSH (US) or CEN (EU).

有光气法和氧硫化碳法。1.光气法 将气与六甲撑亚胺反应生成六甲撑甲酰氯,进而在过量碱存在下与乙硫醇进行巯基化反应而得。亦可将光气先与乙硫醇反应生成S-乙基硫代氯甲酸酯,再与六甲撑亚胺反应而得。2.氧硫化碳法 氧硫化碳在碱作用下与六甲撑亚胺反应,生成N,N-六甲撑硫化氨基甲酸钠,再与硫酸二乙酯或其他乙基化剂反应而得。氯甲酸友谊赶乙酯的制备 在冷却条件下,于20~30℃将光气通入到乙硫醇和催化剂混合液中,然后反应混合物在没有外部冷却的情况下(保持干冰冷凝器)继续搅拌几小时,反应结束后用空气于20~30℃将过量光气驱除,反应混合物用4.5%盐酸和水洗涤,硫酸镁干燥,过滤,滤液真空回流除去挥发性杂质,回流冷凝中冷却水维持在氯甲酸硫赶乙酯能冷凝而硫醇不冷凝的温度,被蒸馏物温度保持恒定10min,停止回流。
六次甲基亚胺的制备 在氢气和己内酰胺混合物露点以上温度形成蒸气混合物,并将该蒸气混合物通过240~270℃的加氢催化剂(预先需用脂肪族或脂环族烃C5~C6处理),配比为氢:己内酰胺=(10~100):1 (mol),压力5×105~10×105Pa,己内酰胺转化率为80%~100%,以转化的己内酰胺计,产率为97%~98%。
实例:将11.0标准m3/h氢和0.8kg/h己内酰胺加入到蒸发器中,蒸气混合物温度维持在240℃,即比生成的蒸气混合物露点高40℃,该混合物通入含3.5L Cu-Zn催化剂 (Cu 40%、Zn 8%/硅藻土)的反应器(通入上述蒸气混合物前,将1.3kg环戊烷蒸气先通过反应器)。加氢过程于240℃、10×105Pa下进行,己内酰胺转化率100%,六次甲基亚胺产率为98%。
禾草敌的合成 将含14g (0.35mol)氢氧化钠的200mL水溶液与31.7g (0.32mol)六次甲基亚胺的100mL正戊烷混合后,在冷却下,将37.4g (0.30mol)氯甲酸硫赶乙酯加入到剧烈搅拌的混合物中,反应混合物的温度维持在15~20℃,加料完毕后,继续搅拌5min。静置分离,有机相用稀盐酸(5mL浓盐酸用水稀释至55mL)和水洗涤,无水硫酸镁干燥、过滤,并在蒸气浴上浓缩,残留液减压蒸馏,得禾草敌51.9g,产率92.3%。
