Abstract: Cross-flow microchannel apparatus for producing emulsions includes a pump 9 and a pump 11 which are driven to respectively supply a continuous phase to a concave portion 4 via a supply pipe 10, a supply hole 6 and a supply port 18 and a dispersed phase to a space between the outside of a base 3 and the inside of a concave portion 2 formed in a case 1 via a supply pipe 12 and a supply hole 7. Then, by applying a predetermined pressure to the dispersed phase, the dispersed phase is formed into fine particles via a microchannels 21 and mixed with the continuous phase, thereby forming emulsions. The emulsions are withdrawn to a tank and so on via a withdrawal port 19, a withdrawal hole 8, and a withdrawal pipe 13 for emulsions.

Abstract: The present invention relates to a process of preparing emulsions of hydrolyzable silanes, such as alkoxysilanes, using an oil concentrate. The emulsifiers are initially stirred with water. An oil concentrate is then prepared by adding a hydrolyzable silane to the stirring mixture of emulsifiers and water. Additional water is then dispersed in the oil concentrate to form the desired emulsion. Emulsions prepared by this process have shelf stability that is 6 months or longer.

Abstract: In an apparatus for continuously manufacturing microspheres, a dispersed phase (O) is supplied to a chamber 27 for the dispersed phase inside of a bulkhead member 26 via a supply port 23. Thereafter, the dispersed phase enters into a gap 31 between a plate 22 via a supply port 29 in a base 25. The dispersed phase which enters into the gap 31 grows microspheres (particles) having a certain diameter while passing through a microchannel 33 by pressure applied by, for example, a pump, and is mixed with a continuous phase (W), so that microspheres are produced. The thus-produced microspheres float or are suspended in the continuous phase without needing any particular external force in response to their specific gravity, allowing the microspheres to be generated and withdrawn from a withdrawal port 32 at a significantly reduced pressure in comparison to conventional methods and apparatus.

Abstract: The invention relates to a new lipopolysaccaride biosurfactant, a strain of Acinetobacter calcoaceticus which produces this biosurfactant, and a process for its preparation. The biosurfactant has a high emulsifying capacity, it promotes the biodegradation of hydrocarbons in water and favors the adhesion of microorganisms to the water/oil interface.

Abstract: An oil in water emulsion comprises a continuous aqueous phase and a discontinuous oil phase which is either a hydrophobic liquid which is immiscible with the aqueous phase or is a solid phase obtained by providing an emulsion in the aqueous phase of a solution of potentially solid material in the hydrophobic liquid and converting this solution to a solid phase, and the emulsion is stabilized by the inclusion of water-soluble stabilizing polymer in the aqueous phase and oil solubilizing stabilizing material, generally polymer, in the oil phase. The or each polymer is preferably a copolymer of hydrophilic and hydrophobic groups, preferably being formed by copolymerization of water-soluble monomer and oil-soluble monomer that provide the desired groups in the polymer without further reaction. Partially hydrolyzed polyvinyl alcohol can be used as the water-soluble polymer.
