Abstract
The invention relates to a method for production of a blowing agent from dimethyl(isopropenyethyl)carbinol containing materials that stabilize flotation. The composition of the blowing agent, in weight per cent, is the following: dimethyl(isopropenyethyl)carbinol - 95.0 - 98.0 %; tetramethylbutindiole - 0.1 - 1.5 %; diisopropenylacetylene - 0.1 - 1.0 %; and 2,5-dimethyl-1,4-hexadien-3-one - 1.5 - 2.5 %. The inventive method consists in treating tetramethylbutindiol with an aqueous solution of an acid in the presence of free radical polymerization inhibitors, at the boiling point of the reactive mixture, and in performing simultaneously steam stripping of the blowing agent while maintaining a constant volume of the reaction mixture by reinjecting the aqueous layer (after extraction) into the reaction mixture.

The inactive mixture is brought to a boil and added to it is a mixture of 15 g of DBD in 60 g of water, after which we begin to remove the steam from the aromatic minerals. It does not react with benzene or other miscible with the water disinfectant, returning the extracted water to the reactive mixture. With this, the total volume of the reaction mixture remains unchanged. The process leads to a complete conversion of the DB.
