Summary
-
1.
A study was made of the catalytic dimerization of five oiefins, namely C10-C19 trisubstituted ethylene derivatives, and the products of the hydrogenation of these dinners were prepared.
-
2.
In the course of the dimerization partial isomerization of the dimers occurred.
-
3.
The calculated densities of the resulting C20-C38 isoparaffins of type
(in which R=propyl, butyl, pentyl, hexyl) are extremely close to the experimentally found values. Increase in the length of the side group in isoparaffins of this type from 3 to 6 carbon atoms has no substantial effect on the change in their density and freezing point.
-
4.
With increase in the molecular weight of the isoparaffins obtained there is a sharp increase in their viscosity.
