    摘要： In a process for the epoxidation of propene, comprising the steps: reacting propene with hydrogen peroxide in the presence of a titanium silicalite catalyst and a methanol solvent; separating non-reacted propene and propene oxide from the resulting reaction mixture to provide a solvent mixture comprising methanol and water in a combined amount of at least 90% by weight; and feeding this solvent mixture as a feed stream to a continuously operated methanol distillation column at a feed point in the middle section of said column to provide an overhead product comprising at least 90% by weight methanol and a bottoms product comprising at least 90% by weight water; the addition of a liquid defoamer, having a solubility in the feed stream of less than 10 mg/kg at 25° C. and a surface tension at the liquid air interface of less than 22 mN/m at 20° C., at or above the feed point in an amount exceeding the solubility of the liquid defoamer in the feed stream suppresses foam formation in the methanol distillation column.

    摘要： Provided is a defoaming agent for a liquid detergent, comprising the following components: component A1, a modified polyorganosiloxane formed by reacting a hydrogen-containing polyorganosiloxane, an unsaturated polyether and an α-olefin; component A2, a modified polyorganosiloxane formed by reacting a hydrogen-containing polyorganosiloxane, an unsaturated polyether and a bivinyl-terminated polyorganosiloxane; component B, an organosilicon composition composed of a hydrogen-containing polyorganosiloxane, a polymer composed of an acrylate and an α-olefin, silica and an organosilicon resin; component C, a thickening agent; and component D, water. An excellent compatibility between the modified polyorganosiloxanes A1 and A2 enables the defoaming agent to exhibit an excellent defoaming performance, stability and clarity in a laundry detergent.
