The present invention provides a method for producing a fatty acid ester inexpensively and efficiently by reacting a lipase or an intact mircroorganism containing a lipase, an oil and fat, and a linear lower alcohol in a system containing little or no solvent in the presence of water. The intact microorganism has not been treated with a solvent or the like, and is used as such, so that a fatty acid ester can be prepared in a simple manner. An oil and fat, a natural oil and fat such as a vegetable oil and fat, an animal oil and fat, as well as a waste oil thereof can be used. According to the method of the present invention, a reaction proceeds even in the presence of water, so that waste oils containing a large amount of water can be used as a raw material. Therefore, the waste oil to be dumped into the environment can be recycled, and a biodiesel fuel, which hardly pollutes the environment, can be provided at the same time.

A separator membrane for use in silver-zinc batteries is produced by extruding a blend of two fillers with the same chemical formula but different particle size. A polyolefine polymer and a plasticizer are blended and extruded to form a thin sheet of 1 to 10 mil thickness. The plasticizer is then extracted to leave submicron voids in the membrane. Plasticizers are added as processing aids, and can be either soluble or insoluble in water, and include petroleum oils, lubricating oils, fuel oils, and natural oils such as tall oils and linseed oils. The oil are then extracted from the membrane by conventional procedures such as single stage extraction using a suitable solvent. Commercially available wetting agents known to the art such as dodecylphenoxy polyethoxy ethanol and isooctyl phenyl polyethoxy ethanol are coated onto the sheet to improve wettability. The sheet is then dried, and boiled in distilled water for one minute or more, before being finally dried.

The present invention is related with bioplasticizers or primary oleochemical plasticizers and the improved process for obtaining thereof. It refers primarily to epoxydized oleochemical plasticizers produced from vegetable oils, as substitute of traditional petrochemical plasticizers. The process starts with the epoxydized product of natural oils, such as sunflower, linseed, Jatropha curcas, soybean, etc., which are transesterified with an alcohol such as ethylic or methylic, in the presence of a catalyst such as sodium methoxide or sodium hydroxide in order to produce an alkylic esters mixture of the fatty acids that were present in the oil or oil mixture used as raw material in the epoxydized oil production. When the plasticizer obtained by the process already mentioned is used for the formulation of moldable poly(vinyl chloride), PVC, resins; the resulting plastic films get adequate hardness, static and dynamic thermal stability, and plasticizer extractability by solvents, such as n-hexane, gasoline and oil. Besides, when the PVC resin is formulated with a phthalic or terephthalic plasticizers mixture and the bioplasticizer, the bioplasticizer presents a full range solubility and or compatibility with the remainder of the resin compounds. The oxyrane chemical ring of the bioplasticizer is an excellent chemical neutralizer of the HCL that might be formed from the PVC, due to the action or interference of thermal or UV radiation.

An improved process is provided for the preparation of siloxane-oxyalkylene and siloxane-alkyl copolymer compositions via a hydrosilation reaction in the presence of high boiling point natural vegetable oils as the reaction solvent. The reaction solvent need not be removed from the block copolymer product, and indeed is beneficial to remain with the copolymer particularly when the copolymer is used as a surfactant for polyurethane foam formulations. Soybean oil and linseed oil are the preferred high boiling natural oil solvents when the copolymer product is to be used in the preparation of the surfactants for polyurethane foams. High resiliency polyurethane foam prepared with these natural oils present in the surfactant preparation afforded improved compression sets, wet compression sets and humid aged compression sets. Additionally, the use of the surfactants made with natural oils as a reaction solvent or consequently surfactants post diluted with natural oils when employed in the preparation of polyurethane foam afforded foams with greatly reduced amounts of "glass fogging".
