The pyrolysis of 2,2-dichloro-l , 1 ,I-trifluoroethane was studied over the temperature range of 112(tI26OoK at total reflected shock pressures from -2800 to 3100 torr. Below 1260"K, the decomposition leads to three reaction products which were identified as CF&FCI, CF&FH, and CF3CC13. The results a

Abstract
1,1,2,2โTetramethylcyclopropane (TTMC) has been decomposed in a singleโpulse shock tube. The main reaction process is magnified image Side reactions are unimportant. From comparative rate experiments (with cyclohexene decomposition as standard) the rate expression for these reactions are

Reinvestigation of the gas phase thermal reaction of 1,1,2,2-tetramethylcyclopropanr (699--75g0K) gave for the unimolecular disappearance of reactant, l i ( ~1 1 ~) = 1 015.27-63.93/s sec-l, in good agreement with the original results of Frey and Marshall. However, evidence for a high activation ene
Dilute mixtures of 4-methyl-1 -pentyne have been pyrolyzed in a single-pulse shock tube. The decomposition process involves bond breaking : kn HC=C--CH2(i-C3H7) --+ HC=zC-<:H2.(propyny1) + i-C,H,as nr1I as a molecular reaction: HC=C-CH,(i-C,H,) % C,H4(allene) + C,H, .

## Abstract A check of the data from comparative rate singleโpulse shock tube experiments have been carried out through the use of a new standard reaction, the decyclization reaction of ethylcyclobutane. The rate expressions for cyclohexene and 2,2,3โtrimethylbutane have been found to be in excel
1,a-Butadiene diluted with Ar was heated behind reflected shock waves over the temperature and the total density ranges of 1100-1600 K and 1.36 X mol/cm3. The major products were 1,3butadiene, 1-butyne, 2-butyne, vinylacetylene, diacetylene, allene, propyne, CzHs, CzH4, CzH2, CH4, and benzene, which
5-Methyl-hexanone-2, 3-methyl-pentanone-2, and hexanone-2 have been decomposed in comparative rate single pulse shock tube experiments. The mechanism of decomposition involves the breaking of carbon-carbon bonds as well as molecular processes involving 6-center complexes. The following rate expressi
