The synthesis of solketal in the presence of sulfuric
acid is the most reasonable and economically efficient
technology for production of this compound. A flow
diagram for synthesis of solketal was suggested and its
description was given.
reaction products by the extraction method and that by
the rectification on three columns are approximately the
same in energy expenditure.
Second, the recovery of solketal by the extraction
method requires large flows of benzine in the technological
scheme and, accordingly, a rather large number of vessels
for the starting benzine and that enriched with solketal.
And this entails not only a gross expenditure of energy and
materials, but also a high fire hazard of the installation. In
view of these data, the technological scheme for recovery
of solketal by the extraction method is not considered an
industrially usable technology.

The experiments performed in the study demonstrated
that two catalysts can be used for industrial production of
solketal: beta zeolite manufactured y AO Angarsk Plant
of Catalysts and Organic Synthesis and sulfuric acid.
The technological scheme based on the application of a
heterogeneous catalyst has a number of disadvantages,
the main of which are the following: need to introduce
and additional component (ethanol) for homogenizing the
reaction mixture and, accordingly, to install and additional
reactor with a stirrer for dissolution of the starting reagent;
gradual deactivation of the catalyst; impossibility of
recycling the unreacted glycerol; and high cost of the
catalyst. The technological scheme with sulfuric acid is
devoid of these shortcoming, is very simple and reliable,
and can provide a nearly 100% yield of solketal due to
the recycling of glycerol.
