Light-sensitive mixture from polycondensation products of diazonium salts, and light-sensitive recording material from them

Light-sensitive mixture from polycondensation products of diazonium salts, and light-sensitive recording material from them. Walls, John E.; Dhillon, Major S. (American Hoechst Corp., USA). Eur. Pat. Appl. EP 89506 A2 28 Sep 1983, 22 pp. DESIGNATED STATES: R: DE, FR, GB, NL. (German). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: G03F007-08. APPLICATION: EP 83-101809 24 Feb 1983.There are some reagents with their cas registry numbers 2160-93-2 and 3453-83-6 are used in this study. PRIORITY: US 82-359336 18 Mar 1982. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The photosensitivity of photosensitive compns. based on a diazonium salt polycondensation product for use in prepg. presensitized recording materials is increased by the addn. of an unsubstituted or azo- or hydroxy-substituted amine. Thus, to 99.25 g of a soln. contg. 2-methoxyethanol 26.37, MeCOEt 34.43, EtOH 25.55, di-Me phthalate 0.48, p-toluenesulfonic acid 0.35, maleic anhydride-styrene () copolymer 1.91, hydroxypropyl cellulose 0.012, Calcozin Yellow 1.64, Rhodamine 6 GDN 0.66, Victoria Pure Blue FGA 0.60, and a diphenylamine-4-diazonium sulfate-paraformaldehyde condensation product isolated as the hexafluorophosphate 8.00 wt.% was added 0.75 g of Ph2NH with 20-30 min stirring at room temp. After filtering, the soln. was coated on a support, dried, exposed through a 21 step wedge, and developed to show 1 covered and 1 partially covered step vs. O covered and 1 partially covered step for a Ph2NH-free control. .

Protodesulfurization of mesitylenesulfonic acid in hydrochloric acid solutions

Protodesulfurization of mesitylenesulfonic acid in hydrochloric acid solutions. Kozlov, V. A.; Bagrovskaya, N. A. (Khim.-Tekhnol. Inst., Ivanovo, USSR). Izv. Vyssh. Uchebn. Zaved.In this article, certain chemicals are used. One of their cas registry numbers is 3453-83-6 , Khim. Khim. Tekhnol., 29(9), 44-7 (Russian) 1986. CODEN: IVUKAR. ISSN: 0579-2991. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The title reaction was studied in 1-17% HCl at 342-414 K, and a linear relation was found between the logarithm of the rate const. and the acidity function (-H0). The slope of the corresponding plot was ~1. A solvated proton attacked a 2,4,6-Me3C6H2SO3-×××H3O+ ion pair to form 2,4,6-Me3C6H2SO3H×H3O+ in a fast step; this was followed by rate-detg. monomol. decompn. to mesitylene and H3SO4+ via a cyclic, solvated s-complex transition state. .
