Process for preparing mixed cyclic organosiloxanes

Claim 1

A PROCESS FOR THE PRODUCTION OF CYCLIC ORGANOSILOXANES OF SPECIFIC DESIRED COMPOSITION HAVING MIXED ORGANOSUBSTITUENTS WHICH COMPRISES REACTING IN THE PRESENCE OF AN INERT SOLVENT AN ORGANOSILOXANE DIOL HAVING THE FORMULA HO(R2SIO)NH WITH AN ORGANOSILANE COMPOUND IN AN AMOUNT SUFFICIENT TO REACT WITH ALL OF THE ORGANOSILOXANE DIOL PRESENT, SAID ORGANOSILANE COMPOUND HAVING THE FORMULA R2SICL3 WHEREIN R AND R1 ARE SELECTED FROM THE CLASS CONSISTING OF MONOVALENT HYDROCARBY RADICALS CONNECTED TO SILICON THROUGH A CARBON-SILICON BOND AND MONOVALENT SUBSTITUTED HYDROCARBYL RADICALS BEING SELECTED FROM THE CLASS CONSISTING OF SUBSTITUTED ALKYL GROUPS, SUBSTITUTED ALKENYL GROUPS, SUBSTITUTED ARYL GROUPS, SUBSTI TUTED ALICYCLIC GROUPS, SUBSTITUTED ARALKYL GROUPS, AND SUBSTITUTED ALKARYL GROUPS AND CONTAINING SUBSTITUENTS FREE OF ACTIVE HYDROGEN, SAID MONOVALENT SUBSTITUTED HYUDROCARBYL RADICALS CONNECTED TO SILICON THROUGH A CARBON-SILICON BOND AND HAVING THE SUBSTITUENTS LOCATED AT LEAST TWO CARBON ATOMS FROM THE SILICON ATOM AND WHEREIN R AND R1 ARE DIFFERENT RADICALS, N IS AN INTEGER HAVING A VALUE FROM 2 TO 4 INCLUSIVE, AND RECOVERING THE DESIRED CYCLIC ORGANOSILICON PRODUCT.
