    • This invention relates to a method of synthesizing certain 3-(carbocyclic aryl)-3-(4'-OP-carbocyclic aryl)-2,3-dihydrobenz[d]isothiazole-1,1-dioxides (and -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides) by reacting (a) a 4-OP-carbocyclic aryllithium compound wherein P is a protecting group and (b) a 3-(carbocyclic aryl)benz[d]isothiazole-1,1-dioxide wherein said 3-(carbocyclic aryl) moiety is other than a 3-(4'-OP-carbocyclic aryl) moiety to give (c) the corresponding 3-carbocyclic aryl)-3-(4'-OP-carbocyclic aryl)-2,3-dihydrobenz[d]isothiazole-1,1-dioxide. The -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides are prepared in the same manner by reacting a 3-(carbocyclic aryl)naphtho[1,8-de]-1,2-thiazine-1,1-dioxide with said 4'-OP-carbocyclic aryllithium compound.In a further embodiment, the compounds synthesized according to the foregoing method are reacted with a carboxylic acid halide to give the corresponding 2-carbonyl-substituted 2,3-dihydrobenz[d]isothiazole-1,1-dioxide (or -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides) followed by removing the protecting group, P, with weak acid to yield certain phenol and 1-naphthol sulfam(na)phthaleins useful, e.g., as optical filter agents and filter agent precursors in photography.

    • A method of treating particulate biodegradable organic waste by thermal hydrolysis. The method includes subjecting a quantity of the particulate biodegradable waste to thermal hydrolysis at a temperature above about 130° C. and a pressure at or above the saturated water vapor pressure to produce a slurry. The slurry will include solubilized organic material and unhydrolyzed residual solids. The method further includes decreasing the pressure at which the slurry is maintained. Typically, the step of decreasing slurry pressure will occur in a flash tank, which allows the separation of an organic acid-rich steam from other hydrolysis products. The method further includes capturing the steam or other condensable gases released when pressure is decreased and condensing the steam or other condensable gases into a condensate. The captured condensate may then be added to a quantity of particulate biodegradable waste prior to thermal hydrolysis. Also disclosed is an apparatus for practicing the method described above.
    • 通过热水解处理颗粒生物降解有机废物的方法。 该方法包括使一定量的颗粒生物可降解废物在高于约130℃的温度和等于或高于饱和水蒸气压的压力下进行热水解以产生浆料。 浆料将包括溶解的有机材料和未水解的残留固体。 该方法还包括降低保持浆料的压力。 通常,降低浆料压力的步骤将发生在闪蒸罐中,其允许有机酸富含蒸汽与其它水解产物分离。 该方法还包括捕获当压力降低时释放的蒸汽或其它可冷凝气体,并将蒸汽或其它可冷凝气体冷凝成冷凝物。 然后在热水解之前将捕获的冷凝物加入到一定量的可生物降解的颗粒物中。 还公开了用于实施上述方法的装置。
