专利号:US-2023111600-A1 优先权日:2019-12-17 标题 :Polymeric fatty acid compounds for the treatment of fibrous amino acid-based substrates, especially hair 发明人:WAGNER ROLAND; STREICHER KATHARINA; ROHMANN LAURA; WENSKE CHRISTIAN; HAVELI SHRUTISAGAR DATTATRAYA 权利人:MOMENTIVE PERFORMANCE MAT GMBH 摘要:The present invention is directed at mono-, di- or polyquaternary ammonium compounds of the formula (I) wherein x is 1 to 50, and F can be the same or different and is represented by the general formula (II) wherein at least one of the optionally substituted and optionally functional-group-containing hydrocarbon radicals R 1 , R 2 , R 3 , R 4 or R 5 contains at least one estolide moiety comprising two or more ester or amide moieties. The invention also relates to a process for the synthesis of such compounds, the use of the compounds in cosmetic formulations for skin and hair care, cosmetic compositions for the treatment of fibers, and compositions containing one or more of the compounds for the treatment of hair.
专利号:US-4709028-A 优先权日:1987-02-03 标 题 :Synthesis of heterocyclic amines via the reaction of dialkylene glycol and ammonia 发明人:JOHNSON THOMAS A; COOPER CAWAS A 权利人:AIR PROD & CHEM 摘要:This invention relates to an improved process for producing a heterocyclic amine, e.g., morpholine and its derivatives by reacting ammonia and a dialkylene glycol. The improvement resides in adding an inert solvent in the form of an alkyl ether of a polyalkylene glycol with said feed. By including such inert solvent one reduces heavies formation particularly at high conversion.
专利号:EP-1964868-A1 优先权日:2007-03-01 标题:Low migration polyurethanes 发明人:FRANKEN UWE; KREBS MICHAEL 权利人:HENKEL AG & CO KGAA 摘要:The invention relates to crosslinking 1-component or 2-component polyurethane compositions, wherein an NCO-reactive isocyanate reaction product is contained and / or Isocyanatumsetzurigsprodukt has been used as a synthesis block in the synthesis of a polyurethane prepolymer contained in the polyurethane composition, said isocyanate reaction product is a reaction product of polyols and aromatic diisocyanates, has a molecular weight between 300 to 3000 g / mol and at least two NCO groups, and the 1 K or 2K polyurethane composition after crosslinking contains only small amounts of migratable aromatic di- or polyamines. Furthermore, the use of such Isocyanatumsezungsprodukte is described as a reactive constituent in crosslinkable polyurethane compositions and moldings produced therefrom.
专利号:US-10843990-B2 优先权日:2018-02-09 标题 :Processes for preparing calix[4]arenes from calix[8]arenes 发明人:HAASE CORNELIUS; HISCOCK JEFF; ATWOOD PHILIP DAVID 权利人:SI GROUP INC 摘要:This invention relates to a one-pot synthesis of a high-purity calix[4]arene compound by reacting a phenolic compound and an aldehyde in the presence of at least one nitrogen-containing base as a catalyst to form the calix[8]arene compound, and cleaving the calix[8]arene compound into a high-purity calix[4]arene compound, directly, without carrying out a purification step before the cleaving step. The invention also relates to an improved conversion of a calix[8]arene compound to a calix[4]arene compound, by cleaving a calix[8]arene compound in a glycol ether solvent having a boiling point of at least about 200° C., to result in a high-purity calix[4]arene compound, without using an antisolvent.
