General Description

2,5-DIMETHYLHEPTANE is a hydrocarbon compound with the molecular formula C9H20. It is a colorless liquid with a mild, gasoline-like odor, and is insoluble in water but soluble in organic solvents. 2,5-DIMETHYLHEPTANE is commonly used as a solvent and as a fuel additive in gasoline to improve combustion and performance. It also has applications in the production of chemicals, pharmaceuticals, and other industrial products. 2,5-DIMETHYLHEPTANE is flammable and should be handled with caution in a well-ventilated area.

Alkene oligomerization process

A process for oligomerising alkenes having from 3 to 6 carbon atoms which comprises contacting a feedstock comprising a) one or several alkenes having x carbon atoms, and, b) optionally, one or several alkenes having y carbon atoms, x and y being different, with a catalyst containing a zeolite of the MFS structure type, under conditions to obtain selectively oligomeric product containing predominant amounts of certain oligomers. The process is carried out at a temperature comprised between 125 and 175° C. when the feedstock contains only alkenes with 3 carbon atoms and between 140 and 240° C., preferably between 140 and 200° C. when the feedstock contains comprises at least one alkene with 4 or more carbon atoms.

A solvent effect in reactions of singlet methylene

The effect of several solvents on the selectivity of singlet methylene (1:CH2) was investigated. It was found that product ratios from reactions in pentane, ethyl ether and cyclohexene solutions were identical; however, product ratios from reactions carried out in benzene were slightly different.
