用途:

LQ-TBHP是一种常用的自由基反应的引发剂，其特点是热稳定性好，易于控制，在50℃以下，其活性在三个月内无明显变化，且无须费用较高的冷冻贮存，可用于乳液聚合、水相聚合、固化及接技聚合等领域，在许多方面的性能优于过二硫酸盐、异丙苯过氧化氢和过氧化苯甲酰。TBHP的分解产物主要为叔丁醇等，无腐蚀性，对设备要求不高。而其它引发剂多数都会形成酸性副产物。

LQ-TBHP同时也广泛地应用于苯乙烯，丙烯酸和甲基丙烯酸的聚合引发剂。

LQ-TBHP是橡胶的硫化剂。可用以改善柴油的十六烷值。同时它也是一种十分重要的有机合成中间体，它对环氧化有特殊的选择性和高收率，是一种十分重要的氧化剂。

贮存条件:

保持包装密闭并处于良好通风状态下，贮存温度≤40℃，避免和还原剂如胺类、酸、碱、重金属化合物（促进剂及金属皂），严禁在库房内分装及取用。

贮存稳定性:

按厂家提示的条件进行保存，产品在六个月内可保证出厂技术标准。

灭火：

小的火灾需用干粉或二氧化碳灭火器灭火，同时用大量水喷洒，防止再燃。大火需在不危险的距离之外用大量水喷射。

Small packaging can also be packaged according to user specifications.

LQ-BCHPC is a Class F solid organic peroxide, with a cargo classification of 5.2 and a United Nations number of 3109. It is a Class II dangerous goods packaging

Safety precautions:

(1) Keep away from sparks, open flames, and heat sources.

(2) Avoid contact with reducing agents (such as amines), acids, bases, and heavy metal compounds (such as accelerators, metal soaps, etc.)

(3) Please refer to the Safety Data Sheet (MSDS) of this product.

Purpose:

LQ-TBHP is the most commonly used initiator for free radical reaction. It is characterized by good thermal stability, safe use, easy control, no significant change in its activity within three months at temperatures below 50 ℃, and no need for costly frozen storage. It can be used in lotion polymerization, aqueous polymerization, curing, grafting polymerization and other fields. Its performance is better than that of persulfate, cumene hydroperoxide and benzoyl peroxide in many aspects. The decomposition products of TBHP are mainly tert butanol , which are non corrosive and do not require high equipment requirements. Most other initiators will form acidic byproducts.

LQ-TBHP is also widely used as a polymerization initiator for styrene, acrylic acid, and methacrylic acid.

LQ-TBHP is a vulcanizing agent for natural rubber. It can be used to improve the cetane number of diesel oil. At the same time, it is also a very important organic synthesis intermediate, with special selectivity and high yield for epoxidation, and is a very important oxidant.

Storage conditions:

Keep the packaging sealed and in a well ventilated state, with a maximum storage temperature of 40 ℃. Avoid mixing with reducing agents such as amines, acids, alkalis, and heavy metal compounds (accelerators and metal soaps). It is strictly prohibited to pack or use in the warehouse.

Storage stability:

Store according to the manufacturer's instructions, and the product can meet the factory technical standards within six months.

Fire extinguishing：

Small fires need to be extinguished with dry powder or carbon dioxide fire extinguishers, and a large amount of water should be sprayed to prevent reignition. A large fire requires spraying a large amount of water from a safe distance.
