Isolation and thin-layer chromatography identification of hexylresorcinol

Isolation and thin-layer chromatography identification of hexylresorcinol. Determination by ultraviolet and visible spectrophotometry. Buchheister Machmer, Manfred (Fac. Farm., Univ. Los Andes, Merida, Venez.). Rev. Fac. Farm., Univ. Los Andes, 19, 5-51 (Spanish) 1978. CODEN: RFFUA3. ISSN: 0543-517X. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Hexylresorcinol (I) [136-77-6] is sepd. from other components of pharmaceutical prepns. by thin-layer chromatog. on silica gel and identified spectroscopically. It is quant. detd. by measuring its absorption at 206 nm or at 460 nm following reaction in alk. medium with diazotized p-nitroaniline. Applications of the methods are given.

Impact-resistant resin mass. Talsma, Herbert; Giffen, William Martin, Jr. (Standard Oil Co. (Ohio), USA). Ger. Offen. DE 2659467 28 Jul 1977, 21 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08L033-20. PRIORITY: US 76-649222 15 Jan 1976. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) The impact strength of impact acrylonitrile-butadiene-methyl acrylate copolymer (I) [27012-62-0] was increased by the addn. of clove oil, eugenol [97-53-0], citral [5392-40-5], cinnamyl alc. [104-54-1], isosafrole [120-58-1], trans-cinnamaldehyde [14371-10-9], cineole [470-82-6], anisole [100-66-3], (RO)3PO (R = C1-4 alkyl), 2-ethylhexanoic acid [149-57-5], p-nonylphenol [104-40-5], 4-hexylresorcinol [136-77-6], benzil [134-81-6], benzyl ether [103-50-4], epoxidized soybean oil, or another oil. Thus, I contg. 10% eugenol had impact strength 3.4 ft. lb./in., compared with 1.2 ft. lb./in. without eugenol.
