用途:

LQ-TBHP是一種常用的自由基反應的引發(fā)劑，其特點是熱穩(wěn)定性好，易于控制，在50℃以下，其活性在三個月內(nèi)無明顯變化，且無須費用較高的冷凍貯存，可用于乳液聚合、水相聚合、固化及接技聚合等領域，在許多方面的性能優(yōu)于過二硫酸鹽、異丙苯過氧化氫和過氧化苯甲酰。TBHP的分解產(chǎn)物主要為叔丁醇等，無腐蝕性，對設備要求不高。而其它引發(fā)劑多數(shù)都會形成酸性副產(chǎn)物。

LQ-TBHP同時也廣泛地應用于苯乙烯，丙烯酸和甲基丙烯酸的聚合引發(fā)劑。

LQ-TBHP是橡膠的硫化劑。可用以改善柴油的十六烷值。同時它也是一種十分重要的有機合成中間體，它對環(huán)氧化有特殊的選擇性和高收率，是一種十分重要的氧化劑。

貯存條件:

保持包裝密閉并處于良好通風狀態(tài)下，貯存溫度≤40℃，避免和還原劑如胺類、酸、堿、重金屬化合物（促進劑及金屬皂），嚴禁在庫房內(nèi)分裝及取用。

貯存穩(wěn)定性:

按廠家提示的條件進行保存，產(chǎn)品在六個月內(nèi)可保證出廠技術(shù)標準。

滅火：

小的火災需用干粉或二氧化碳滅火器滅火，同時用大量水噴灑，防止再燃。大火需在不危險的距離之外用大量水噴射。

packing:

The standard packaging is a polyethylene plastic drum with a net weight of 25 kilograms or 180 kilograms, which can also be packaged in IBC or transported by tank car. However, it is important to pay special attention to the SADT of 55 ℃ and the critical temperature of 50 ℃ when packaged in IBC or tank car. 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.
