    摘要： An improvement in a continuous process for making high internal phase emulsions that are typically polymerized to provide microporous, open-celled polymeric foam materials capable of absorbing aqueous fluids, especially aqueous body fluids such as urine. The improvement involves recirculating a portion (about 50% or less) of the emulsion withdrawn from the dynamic mixing zone of this continuous process. This increases the uniformity of the emulsion ultimately obtained from this continuous process in terms of having the water droplets homogeneously dispersed in the oil phase. This also improves the stability of the HIPE and expands the temperature range for pouring and curing this HIPE during subsequent emulsion polymerization. The improvement also eliminates the need for a static mixer outside the dynamic mixing zone, and allows for processing where relatively low pressure drops are required across the mixing zone.

    摘要： An HIPR emulsion of oil in water is prepared by a method comprising the steps of (a) generating a foam by beating a gas into an aqueous solution of a surfactant and (b) dispersing the foam into the oil under low shear conditions in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising distorted oil droplets having mean droplet diameters in the range 2 to 50 microns, separated by aqueous films, 70 to 98% by volume of the liquid content of the emulsion being oil.The method is applicable to both high and low viscosity oils.Depending on the nature of the oil, the emulsions can be used in the food, drug, cosmetics and petroleum industries.

    摘要： A method for forming a stable emulsion of a viscous hydrocarbon in an aqueous buffer solution includes the steps of: providing a viscous hydrocarbon containing an inactive natural surfactant and having a salt content by weight of less than or equal to about 15 ppm and having a water content by weight of less than or equal to about 0.1%; forming a solution of a buffer additive in an aqueous solution to provide a basic aqueous buffer solution, the buffer additive being operative to extract and activate the inactive natural surfactant from the viscous hydrocarbon; and mixing the viscous hydrocarbon with the aqueous buffer solution at a rate sufficient to provide an emulsion of the viscous hydrocarbon in the aqueous buffer solution, whereby the buffer additive extracts the inactive natural surfactant from the viscous hydrocarbon into the aqueous buffer solution and activates the inactive natural surfactant so as to stabilize the emulsion. According to the invention, the buffer additive is a water soluble amine. The inactive natural surfactant contained in the viscous hydrocarbon includes carboxylic acids, phenols, esters, and mixtures thereof. Bimodal emulsions, having two distinct droplet size distributions, are also formed according to the method of the present invention and have improved viscosity characteristics.
