Pyrolysis products from

Heating the white reaction product to 140 C for one hour in vacuum caused a visible iodine evolution and approximately 40% weight loss. No further weight loss was observed up to 250°C. The gaseous products from the pyrolysis were not collected. The green product from pyrolysis analyzed Pu, 43 3% I, 50 2% C, 4.9 1%. The empirical formula PuI2C2H3 has the calculated composition Pu, 45.88% I, 48.75% C, 4.79%.

Direct extrusion of methyl nitrene has been discounted as an explanation of these deamination reactions, which are apparently induced by attack of the acetylenic ester and thus more likely take place via an intermediate analogous to 176. On the other hand, the products from pyrolysis of 107 at 325° include 1,2,3,4-tetrafiuoronaphthalene (132) and hydrogen cyanide, and it was suggested that methyl nitrene was the precursor of the latter compound (see Section III,D). The adduct (180) of tetrafiuorobenzyne and thiophen extrudes sulfur so readily...

Decrease in pH. After heating at 140°C for 20 min, the pH of milk has decreased to about 5.8 due to acid production from pyrolysis of lactose, precipitation of soluble calcium phosphate as Ca3(P04)2, with the release of H+, and dephosphorylation of casein with subsequent precipitation of the liberated phosphate as Ca3(P04)2 with the release of H+. The heat-induced precipitation of Ca3(P04)2 is partially reversible on cooling so that the actual pH of milk at 140°C at the point of coagulation is much lower than the measured value and is probably below 5.0. 

V (at oxygen consumption over 90%) indicates that Reactor III gave the highest selectivity (ca. 60% ) as to hydrogen peroxide formation, and the lowest yield of by-products from pyrolysis and combustion. Reactor... 

Thus, by shifting a methyl group from Si to N, the mechanism of transformation has been changed entirely. The products from pyrolysis of — [ NMe] — and —[MeHSiNHR— are quite different as clearly seen in Figure 4, which compares the 29Si NMR spectra for both materials pyrolyzed to 1000 °C. This is proof that polymer architecture can strongly influence the type of ceramic material produced on pyrolysis. 

There is a difficulty with the mechanism of Scheme 3 in that the fragmentation of a triplet diradical should conserve spin, yet neither triplet Me2Si nor triplet tetraphenyl-naphthalene have been detected. The diradical pathway for the photofragmentation of silanorbornadienes confirms an earlier proposal by Barton and coworkers52. There is always the possibility that diradical intermediates such as the singlet and triplet 13 S and 13 T could function as silylenoids. Thus, the assumption that products from pyrolysis of 7-silanorbornadienes are formed from free silylenes must be treated with caution.

The iron carbonyl-promoted [3 + 4] cycloaddition of bromo-ketones to. 1,3-dienes provides a convenient way, via 2-oxyallyIs, of synthesizing tropones and hence thujaplicins. The synthesis of nezukone (154 X = H)253 has been reported from a,a,a, a -tetrabromoacetone and 3-isopropylfuran. Similarly, from 2-isopropylfuran, /3-thujaplicin (154 X = OH) has been synthesized from the corresponding tropone by known methods, and a-thujaplicin synthesis requires isopropyl substitution in the ketone moiety.254 Karahanaenone (155) is a minor product from pyrolysis of the benzoate (156).149...

Tars are primary products from pyrolysis of biomass or other carbon-containing materials. Their formation cannot be avoided. However, these primary tars are not stable. After having evolved from the solid matter, they undergo secondary tar reactions, altering both in mass and composition. As shown in fig. /, secondary tar reactions...
