In a study of the course of thermal explosions in low, high and constant pres-sme autoclave experiments, 3 stages of thermal runaway, initiation and explosion were identified and studied in detail. Most of the work was done with tert-butyl peroxybenzoate, but limited comparative examinations were carried out on 8 other energetic substances.

The oxidation of oxazoline 58 to oxazole 60 turns out to be problematical in Pattendens synthesis. Even with special oxidation techniques (tert-butyl peroxybenzoate 59/copper (I) bro-... 

Residual monomers in the latex are avoided either by effectively reacting the monomers to polymer or by physical or chemical removal. The use of tert-butyl peroxypivalate as a second initiator toward the end of the polymerization or the use of mixed initiator systems of K2S2Og and tert-butyl peroxybenzoate (56) effectively increases final conversion and decreases residual monomer levels. Spray devolatilization of hot latex under reduced pressure has been claimed to be effective (56). Residual acrylonitrile also can be reduced by postreaction with a number of agents such as monoamines (57) and dialkylamines (58), ammonium—alkali metal sulfites (59), unsaturated fatty acids or their glycerides (60,61), their aldehydes, esters of olefinic alcohols, cyanuric acid (62,63), andmyrcene (64). 

Two peroxides are preferably used for the production of EPS (a) dibenzoyl peroxide (BPO), to initiate the first stage of the polymerization at a temperature of about 90 °C, and (b) tert-butyl peroxybenzoate (/er/BuPB), for the second stage in a temperature range of 115-130 °C. A typical time-temperature regime for the production of EPS using both of these initiators is given in Figure 9.3. 

To trimethyl(vinyl)silane (26.0 g, 259 mmol) and tert-butyl peroxybenzoate (1.02 g, 5 mmol) in MeOH (100 mL) was slowly added NaHSOs (52.6 g, 505 mmol) in HjO (100mL) at rt. The mixture was refluxed for 48 h, carefully concentrated (CAUTION peroxides ) and H2O was removed by azeotropic distillation with MeOH (3 x) by rotary evaporation. The residue was extracted with MeOH (3 x with a total of 250 mL), and the resulting soln was taken to dryness and dried at 150 °C under reduced pressure giving sodium 2-(trimethylsilyl)ethanesulfonate yield 37.0 g (70%).

The linearity, of this order, of the self-heating process or curve, of 2 cm of a chemical of the TD type subjected to the adiabatic self-heating test started from a Ts, recorded for the time, A t, required for the temperature of the chemical to increase by the definite value of AT of. 25 K from the r is exemplified by a digital record of the self-heating process, which is presented in Table 5 in Section 4.7, of 2 cm of 99 % tert-butyl peroxybenzoate (TBPB) charged in the open-cup cell and subjected to the adiabatic self-heating test started from a nominal T, of 76 °C, for the time, At, required for the temperature of TBPB to increase by the definite value of AT of. 25 K from the nominal T. ... 

Tsuji s group coupled 2-methylfuran with ethyl acrylate to afford adduct 15 via a Pd-catalyzed Fujiwara-Moritani/oxidative Heck reaction using tert-butyl peroxybenzoate to reoxidize Pd(0) to Pd(II) [30]. The palladation of 2-methylfuran takes place at the electron-rich C(5) in a fashion akin to electrophilic aromatic substitution. The perbenzoate acts as a hydrogen acceptor.
