Abstract: According to one embodiment, an actinic-ray- or radiation-sensitive resin composition includes an arylsulfonium salt that when exposed to actinic rays or radiation, generates an acid, the arylsulfonium salt containing at least one aryl ring on which there are a total of one or more electron donating groups, the acid generated upon exposure to actinic rays or radiation having a volume of 240 ?3 or greater.

Abstract: Stable, topically applicable cosmetic/dermatological sunscreen compositions, well suited for the UV-photoprotection of human skin/keratinous materials, contain a thus effective amount of at least one novel amine, amide, sulphonamide or carbamate substituted benzalmalonic salt compound.
Abstract: The present invention is a process for producing phenyl-alkanes by paraffin adsorptive separation followed by paraffin dehydrogenation and then by alkylation of a phenyl compound by a lightly branched olefin. The adsorptive separation step employs a silicalite adsorbent and, as the desorbent, a C5-C8 linear paraffin, a C5-C8 cycloparaffin, a branched paraffin such as isooctane, or mixtures thereof. The effluent of the alkylation zone comprises paraffins that are recycled to the adsorptive separation step or to the dehydrogenation step. This invention is also a process that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups that to produce modified alkylbenzene sulfonates. In addition, this invention is the compositions produced by these processes, which can be used as detergents having improved cleaning effectiveness in hard and/or cold water while also having biodegradability comparable to that of linear alkylbenzene sulfonates, as lubricants, and as lubricant additives.

Abstract: The reaction product of:(a) a compound of the formula: ##STR1## wherein X is a member selected from the group consisting of N, O and S; R.sub.1 and R.sub.2 are independently a straight or branched, saturated or unsaturated non-aromatic hydrocarbon of four to eighteen carbon atoms; m is 1 or 2; and n is 0, 1 or 2; and(b) a compound selected from the group consisting of primary, secondary, tertiary and higher amines, which are liquid at room temperature.The reaction product of the present invention has excellent surfactant properties, and is suitable for use in coloring compositions to improve the fugitivity from skin and clothing. The reaction product is also useful as a cleansing agent.
Abstract: A fluorided silica-alumina catalyst, particularly one with a silica:alumina ratio in the range of 1:1-9:1 containing from 1 to 6 weight percent fluoride, is particularly effective in the liquid phase alkylation of benzene by linear olefins to produce linear alkyl benzenes at temperatures no greater than 140.degree. C. These catalysts also are effective in the liquid phase alkylation of alkylatable aromatics generally with a variety of alkylating agents, including olefins, alcohols, and alkyl halides.
Abstract: This invention is directed to neutral and low overbased alkylphenoxy sulfonates derived from alkylphenols prepared by alkylating phenol with an acidic alkylation catalyst having a Hammett (H.sub.o) acidity function of about -2.3 or less (more negative).

Abstract: Silica-aluminas having a sodium content less than about 0.1 weight percent show increased stability when used as a catalyst for the alkylation of aromatic compounds. Where such silica-aluminas are used as the catalyst in detergent alkylation their increased stability permits continuous alkylation to be performed at lower temperatures, as a result of which the detergent alkylate product shows an incrementally higher linearity. Fluorided silica-aluminas having a sodium content of under 0.05 weight percent are particularly advantageous.
