过氧化苯甲酰

过氧化苯甲酰用途

【用途一】
用作分析试剂、氧化剂、漂白剂及塑料聚合引发剂
【用途二】
用作聚氯乙烯、不饱和聚酯类、聚丙烯酸酯等的单体聚合引发剂，也可作聚乙烯的交联剂，还可作橡胶硫化剂
【用途三】
用作不饱和聚酯树脂的固化剂
【用途四】
小麦粉增白剂；氧化剂；漂白剂。
【用途五】
作为面粉品质改良剂，具有杀菌作用和较强的氧化作用，能使面粉漂白。我国规定仅用于小麦粉，最大使用量0.06g/kg。
【用途六】
日本生产的过氧化苯甲酰商品，除纯度98.0％粉末型外，还有多种商品化规格，例如糊型(本品50％与增塑剂50％)、液型(本品75％与水25％)、面粉熟化漂白型(将本品19％～22％用明矾、磷酸钙、硫酸钙、碳酸钙、碳酸或面粉中的一种或两种以上稀释得到)。
粉末型产品主要用作丙烯酸系树脂、MMA树脂等的聚合引发催化剂。近年正在推广作为快速粘合剂应用于高速公路工程等方面，糊型产品用作聚酯树脂成型加工的固化催化剂。液型则作为聚合催化剂用于制备聚苯乙烯树脂。
本品为强氧化剂，对冲击和摩擦敏感，爆炸的危险性很大，应避免与金属粉末，活性炭及还原剂接触。储存时必须以水作稳定剂，含水量30％，仓储温度30℃以下。郑州市食品添加剂厂在1993年6月26日发生过爆炸事故，死亡27人，伤33人。本品有毒，会使皮肤、黏膜产生炎症。小鼠口服LD₅₀为3.949mg/kg。
【用途七】
主要用作PVC、聚丙烯腈的聚合引发剂和不饱和聚酯、丙烯酸酯的交联剂。在橡胶工业中用作硅橡胶和氟橡胶的交联剂。还可作为漂白剂、氧化剂，用于化工生产。

过氧化苯甲酰合成路线

详细合成路线

过氧化苯甲酰上下游产品

过氧化苯甲酰上游产品

过氧化苯甲酰下游产品

过氧化苯甲酰制备

1.冷却条件下在30%的氢氧化钠溶液中加入30%的过氧化氢，生成过氧化钠溶液；然后在0～10℃下搅拌滴加苯甲酰氯，温度过高会引起过氧化氢分解和苯甲酰氯水解；析出反应生成的过氧化苯甲酰，经冷却、过滤、洗涤，并用2：1的甲醇/氯仿重结晶、干燥(50～70℃)得到产品，产率85%以上。

2.在反应釜内先加入40%以上的烧碱溶液0.75份，加水稀释为30%左右，搅拌下冷却至10℃，滴加30%的双氧水1份，控制反应温度为(10±2)℃。滴加完后，通冷冻盐水使物料温度降至0℃左右，再一边搅拌，一边滴加苯甲酰氯。通过调节苯甲酰氯的滴加速度和加强传热，控制反应温度保持在0℃以下。滴加完苯甲酰氯后，继续保持0℃左右，搅拌反应2～3h。然后静置分层，放出下层废液，加入冰水，边加边搅拌。再静置分层。分出下层的过氧化苯甲酰，进行低温干燥，需储存时应保持成品中含水量25%～30%。

3.将30%的烧碱溶液搅拌下冷却至10℃，滴加30%的双氧水。滴加完后，使物料温度降为0℃左右，再滴加苯甲苯酰氯，然后静置分层，分出下层的过氧化苯甲酰，进行低温干燥，保持成品中含水量25%～30%进行储存。

4.由苯甲酰氯与过氧化氢和碱（或过氧化钠）反应，经冷却、过滤、洗涤、重结晶、干燥而得。

5.以碳酸氢铵为碱性介质，在其他原材料不变的情况下，常温反应合成BPO的新工艺　将一定量苯甲酰氯投入苯甲酰氯贮罐中待用；称量相等质量的双氧水投入反应釜中，开启搅拌；然后加入少量相转移催化剂十二烷基硫酸钠，再将称量好的碳酸铵慢慢投入反应釜中。待碳酸氢铵在双氧水中均匀分布后，以一定的流量逐渐滴加苯甲酰氯至反应釜，并视反应釜的温度情况，调节苯甲酰氯的加入量，保持20℃左右，直至苯甲酰氯全部投完为止。待反应釜中无气体放出即为反应结束。开启无堵塞泵，把物料打至离心机脱水即可得到BPO产品。碳酸氢铵苯甲酰氯合成BPO的反应方程式：

6.将22g无水Na2CO3溶于200mL水中，冰水浴下于15℃左右加入14mL30%H2O2、1mL15%活化剂，并保持温度在15℃左右滴加苯甲酰氯28.0g，滴加完毕后再机械搅拌2h，反应中生成白色粒状结晶品，抽滤，水一次，得白色颗粒产品28.0g。碘量法测定过氧化苯甲酰含量99%以上，水分22.5%，收率90%。

7.制法：

于装有搅拌器、温度计、两个滴液漏斗的反应瓶中，加入10%的双氧水100mL，（0.29mol），冰水浴冷却至5℃左右，同时滴加两种液体：苯甲酰氯（1）28.5（0.2mol）和9.5g氢氧化钠溶于60mL水配成的溶液。控制滴加速度，以保持反应液呈弱酸性。反应中不断析出固体。加完后继续搅拌反应直至无苯甲酰氯的气味。抽滤，水洗，而后用冷乙醇浸泡（除去可能存在的苯甲酸和苯甲酰氯），尽量抽干。风干后得过氧化苯甲酰（1）20g，mp106～108℃，收率85%。
