The thermal polymerization of C5 olefins occurs at 260–270° and 1000–3000 Kg/sq.cm. The rate of polymerization depends on the structure of the C5 olefin: 1-pentene and 3-methyl-1-butene polymerize most rapidly, 2-methyl-1 -butene polymerizes somewhat more slowly, and 2-methyl-2-butene and 2-pentene polymerize most slowly. The C5 olefins studied fall into an analogous sequence when placed in order of the degree of polymerization attained.

The “characteristicness” [specificity] of criteria of certain tri- and tetraalkylbenzenes has been examined and made more precise.

Homogeneous destructive hydrogenation of three isomeric butylphenols at 440° and high hydrogen pressures was investigated. The reaction rate decreased in the series o-n-butylphenol> p-n-butylphenol>p-sec-butylphenol. The difference in the rate of total conversion was determined predominantly by the stage in which there was thermal cleavage of the weakest bond of the alkyl group.

An investigation was made of the thermal transformations of 2-methylfuran at 350–375° under high pressures of hydrogen. The liquid products were found to contain acetone, butanone, 2-pentanone, 2-hexanone, 2--heptanone, acetophenone, 2-pentanol, pentane, and water.

The homogeneous destructive hydrogenation of tetralin (1,2,3,4-tetrahydronaphthalene) was investigated at 440–462° and at pressures of up to 1200 atm.
