    摘要: 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.

    摘要: A method for treating particulate biodegradable organic waste includes sizing the waste and adding a base prior to introducing the waste to a thermal hydrolysis reactor and hydrolyzing the waste at a temperature of about 130° C. or greater and a pressure greater than the saturated water vapor pressure to produce a slurry including solubilized organic material and residual solids. The solubilized organic material is separated from the residual solids using a liquid/solid separator and the solubilized organics are subjected to anaerobic digestion to produce a methane gas. The base is preferably potassium hydroxide (KOH) at a concentration of about 1%. The method may further include preheating the particulate biodegradable organic waste with latent heat of the separated solubilized organic material prior to thermal hydrolysis.
