专利号:US-3886201-A 优先权日:1971-11-17 标 题:Perfluoroalkyl esters of mercapto- and thio-carboxylic acids 发明人:FALK ROBERT ALLAN; KLEINER EDUARD KARL 权利人:CIBA GEIGY CORP 摘要:Novel perfluoroalkyl group containing mercaptans and sulfides are disclosed having soil repellent properties if applied to substrates such as textiles, paper and leather and being useful as intermediates for the synthesis of soil repellent polymers. The adducts are obtained by the base or free radical catalyzed addition of hydrogen sulfide or mono- or polymercaptans to perfluoroalkyl group containing esters of fumaric, maleic, citraconic, mesaconic, itaconic, methylene malonic or aconitic acid.
专利号:US-9314021-B2 优先权日:2004-11-03 标题 :Formulations containing insect repellent compounds 发明人:SCIALDONE MARK A 权利人:DU PONT 摘要:Dihydronepetalactone, a minor natural constituent of the essential oil of catmints ( Nepeta spp.) such as Nepeta cataria , has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.
专利号:US-3965148-A 优先权日:1972-08-16 标题 :Perfluoroalkyl alcohols 发明人:KLEINER EDUARD K; FALK ROBERT A 权利人:CIBA GEIGY CORP 摘要:Perfluoroalkyl group containing alcohols are disclosed with utility as intermediates for the synthesis of oil and water repellent fluorochemicals. The alcohols are obtained by the addition of mercaptoalcohols to perfluoroalkyl group containing esters of fumaric, maleic, citraconic, mesaconic, itaconic, methylene malonic or aconitic acids.
专利号:FR-2571365-A1 优先权日:1984-10-05 标题:NOVEL ASPARTIC ACID DERIVATIVES FOR USE IN THE SYNTHESIS OF ASPARTYL PEPTIDES
专利号:WO-2022090277-A1 优先权日:2020-10-30 标 题:N-functionalized fatty acid amides as self-tanning substances 发明人:OSTHOFF JULIAN; VON HAGEN JOERG; CAROLA CHRISTOPHE 权利人:MERCK PATENT GMBH 摘要:The present invention relates to the use of N-functionalized fatty acid amides of formula I as self-tanning substances for skin, for stimulating melanin synthesis, for improving melanin transport, for boosting natural tanning and/or improving the distribution of melanin in suprabasal layers of the skin, and to preparations comprising these amides.
专利号:US-2020038306-A1 优先权日:2016-10-07 标题:Barbituric acid derivatives as self-tanning substances 发明人:OSTHOFF JULIAN; DRILLER HANSJUERGEN; CAROLA CHRISTOPHE; BACK ROBIN; KROHN MICHAEL 权利人:MERCK PATENT GMBH 摘要:The present invention relates to the use of barbituric acid derivatives of the formula I as self-tanning substance, for increasing melanin synthesis, for improving melanin transport and/or improving the distribution of melanin in superbasal layers, to preparations comprising these barbituric acid derivatives, and to specific barbituric acid derivatives.
