ABSTRACT:
A process for producing a hydrogensiloxane represented by the following general formula: ##STR1## wherein R is a monovalent organic group, Me is the methyl group, n is an integer of 1 to 3, and m is 1 or 2, comprises reacting a chlorosilane represented by the following general formula: ##STR2## wherein R, Me, n and m are as defined above, with 1,1,3,3-tetramethyldisiloxane in the presence of water and an acid. The process can produce the hydrogensiloxane in a high yield, since side reactions are effectively obviated.
