Abstract: This invention makes available processes for preparing images, especially color proofs. A layer with imagewise tacky and nontacky areas is toned. Toner adhering to the tacky areas is transferred first onto a temporary support and from there onto an image receptor.

Abstract: Durability of ink jet printheads is improved by employing certain sulfur-containing adhesion promoters between the photoresist intermediate layer and the top plate having a noble metal surface.

Abstract: The present invention provides a fixed bed catalyst for the oxychlorination of ethene, alpha olefins and aromatics. More specifically, this invention relates to a catalyst having an impeded center which excludes reactants, or prevents products from forming in the interior of the catalyst. The impeded center may be made inaccessible or it may be inert to reaction. Thin layers of high specific surface area carrier material cover the outer surface of the impeded center. An agent capable of catalyzing oxychlorination reactions is added to the layered catalytic carrier material.

Abstract: Highly active, improved ethylene oxychlorination catalysts are prepared by forming alumina having specific pore volume characteristics and impregnating such alumina with an oxychlorination catalyst such as CuCl.sub.2. The improved catalysts of the present invention utilize an alumina carrier having a pore volume distribution such that substantially no pores are present which have diameters of less than 150 .ANG.ngstroms and the total alumina carrier has a surface area of at least 30 square meters per gram.

Abstract: A method of removing water from activated carbon is disclosed. Briefly, the method comprises (a) passing liquid 1,2-dichloroethane through a bed of activated carbon until a bulk water phase ceases to exit the bed or until from about 60 to about 80 weight percent of the water present in a water-saturated bed has been removed and (b) removing substantially all of the remainder of the water present by use of vacuum or by passing hot air or hot nitrogen through the activated carbon.

Abstract: A method is provided for the removal of 2-chloroethanol from 1,2-dichloroethane (EDC) mixtures containing chloral comprising(1) placing the EDC/2-chloroethanol mixture at a pH of at least 10,(2) partially distilling said basic mixture to remove ethylene oxide from the resulting mixture of (1),(3) mixing the distillate with water in contact with a strong non-halogen acid catalyst to form an aqueous and organic phase, and(4) recovering the reaction product of (3) while separating and disposing the aqueous phase.

Abstract: An improvement in the method of preparing alkanedisulfonates by the reaction of olefins with bisulfite or sulfite is disclosed. The improvement comprises conducting the reaction in the presence of an effective amount of a C.sub.3 -C.sub.6 monocarboxylic acid.

Abstract: A method for the disposal of 2-chloroethanol by conversion to readily biodegradable ethylene glycol comprising;(1) extracting 2-chloroethanol into a neutral or acidic aqueous solution;(2) adjusting the pH of the solution to at least 10 and heating to a temperature of from about 25.degree. C to about 100.degree. C to form ethylene oxide and ethylene glycol,(3) stripping the basic solution of (2) to obtain a basic aqueous phase and a distillate, the basic aqueous phase being disposed, and(4) condensing and hydrolyzing the distillate and(5) stripping said hydrolysate, recovering the volatile organic portion, and(6) disposing of ethylene glycol in aqueous solution.

Abstract: Air initiation of pendant or internal olefin sulfitation at commercially useful rates and selectivities is achieved by stirring a mixture containing detergent range internal or pendant olefins, an alkali-metal or ammonium bisulfite, an alkali-metal or ammonium sulfite, an alkali-metal or ammonium alkane or alkylbenzene sulfonate surfactant, water, and an alcohol such as 1-propanol or 1-butanol, at ambient temperature and pressure while passing oxygen-containing gas through the mixture at a very slow rate. Bisulfite present must be in a mole ratio with respect to olefin of from 1 to 1-3 to 1 respectively, while sulfite must be present in a mole ratio to olefin of from 1 to 2-2 to 1. PH of the reaction mixture normally ranges from 5 to 6.

Abstract: Reaction rate and olefin conversion in an organic peroxide initiated addition of water soluble bisulfite to olefins having 12 or more carbon atoms can be increased with the addition of a small amount of water soluble sulfite in combination with an organic solvent and agitation. The catalytic effect of the added sulfite in this reaction system unexpectedly increases as the olefin molecular weight increases, thus allowing convenient and economical sulfitation of mixtures in the C.sub.12 to C.sub.22 olefin range.
