Abstract
A process for producing a soluble silicone product is provided. The process includes the steps of chemically reacting a polydialkoxysiloxane with an aliphatic alcohol with or without a catalyst in a reaction mixture, removing produced alcohol from the mixture; recovering the water soluble portion of produced silicone product, purifying the water soluble portion; and recovering hydrophilic material in the water insoluble portion.
Claims19
A method of producing a water soluble silicone comprising:
- chemically reacting a polyalkoxysiloxane with an alcohol by means of a reaction mixture in order to produce a silicone material;
- obtaining a water soluble portion from the produced silicone material by a recovery mechanism;
- and
- recovering any water insoluble residue material produced as a result of carrying out said obtaining step;
- wherein the reacting step is carried out at a temperature of between about 210° F. and 235° F. with a reaction time of between about 5 and 18 hours.
A method of producing a water soluble silicone material comprising:
- chemically reacting a polyalkoxysiloxane with an aliphatic alcohol by means of a reaction mixture in order to produce a silicone product;
- and
- obtaining a water soluble portion from the produced silicone material by an extraction mechanism selected from the group consisting of centrifugation, decantation and filtration,
- wherein the reacting step is carried out at a temperature of between about 225° F. and 235° F. with a reaction time of between about 5 and 8 hours.
A water soluble silicone product prepared by a process comprising the step of chemically reacting a polyalkoxysiloxone with an aliphatic alcohol in a reaction mixture in order to produce a modified silicone material, wherein the reaction is carried out at a temperature of between
- about 225° F. and 235° F. with a reaction time of between about 5 and 8 hours.
