摘要： Provided are an apparatus and method for rapid cooling of a high temperature gas. The apparatus includes one or more cylindrical housings (001) connected to one another, a jacket (002) on an outer side of a housing, an inner cylinder (003) disposed at least in an interior of a first cylindrical housing, a heat insulation gasket (005), inner members (006), a corrosive high temperature gas inlet (N01) disposed on the heat insulation gasket (005), a gas and liquid phase outlet (N02) disposed at a bottom of the housing or a bottom of a last housing and a coolant inlet and outlet (N03-N05) connected to an interior of the jacket (002). The heat insulation gasket (005) seals the first cylindrical housing (001) and a top of the inner cylinder (003) in the interior of the first cylindrical housing (001). The inner members (005) are distributed along a wall of the housing (001), communicate an interior of the jacket (002) with an interior of the housing (001), and distribute a liquid in the interior of the jacket (002) to the interior of the housing (001). The method replaces a filter and a cooler and effectively reduces a risk of blockage when a solid-containing gas is cooled.

摘要： The present invention relates to a method of preparing ethylbenzene hydroperoxide by liquid-phase peroxidation of ethylbenzene and a preparation method of propylene oxide. By adding a small amount of an organic basic substance, the peroxidation between ethylbenzene and an oxygen-containing gas is facilitated. The method can effectively increase the selectivity of a target product, and the added organic basic substance does not affect the activity of a subsequent epoxidation catalyst.
