t-부틸퍼옥시옥토에이트 화학적 특성, 용도, 생산

화학적 성질
Tert-Butyl peroxy-2-ethylhexanoate is a colorless liquid. It has a half-life in benzene of 10.0 h at 162°F (72°C). It is used as a medium temperature initiator for the polymerization of vinyl monomers and the curing of styrene-unsaturated polyester resins. It is regarded as an intermediate fire hazard; however, it has low impact sensitivity .
용도
Tert-Butyl peroxy-2-ethylhexanoate (TBPO), also known as Trigonox 21S or PEROXAN PO-30 , is an initiator for (co)polymerization of ethylene, styrene, acrylonitrile and (meth)acrylates. Curing agent for unsaturated polyester resins. It is used for high pressure polymerization of ethylene in both autoclave and tubular processes, usually in combination with other peroxides of varying degrees of activity.
일반 설명
This peroxide is particularly sensitive to temperature rises and contamination. Above a given "Control Temperature" they decompose violently. tert-Butyl peroxy-2-ethylhexanoate is generally stored or transported with inert solids to mitigate the explosion hazard.
반응 프로필
Tert-Butyl peroxy-2-ethylhexanoate explodes with great violence when rapidly heated to a critical temperature; pure form is shock sensitive and detonable [Bretherick 1979 p. 602]. Decomposes violently or explosively at temperatures 0-10°C owing to self- accelerating exothermic decomposition; Several explosions were due to shock, heat or friction; amines and certain metals can cause accelerated decomposition [Bretherick 1979 p. 156]. Danger of explosion when dry
Synthesis
The synthesis method of commercial peroxyester tert-butyl peroxy-2-ethylhexanoate (TBPEH) is shown below:

The first reaction step is the deprotonation of tert-butyl hydroperoxide (TBHP) with the base (MOH) in the aqueous phase, a homogeneous and slightly exothermic reaction. The base is usually in excess with respect to TBHP to ensure a high enough pH when the reaction has almost completed. Thanks to the TBHP acidity, the equilibrium is shifted to the right and most of the TBHP present in the aqueous phase is deprotonated. The alkali salt of TBHP (MTBP) further reacts with 2-ethylhexanoyl chloride (EHCl) to form TBPEH and a chloride salt (MCl). The reaction is biphasic with MTBP, MOH, MCl and some TBHP in the aqueous phase and EHCl, TBPEH and most of TBHP in the organic phase. The reaction between EHCl and TBHP is very slow and can be neglected[1].
