摘要:
A class of cationic ester surfactants is described which has improved hydrolytic stability. In particular, the present invention relates to the use of quaternized alkanol amine ester compositions wherein the ester is based on a secondary or tertiary alcohol, and/or the use of a quaternized alkoxylated alkanol amine ester in detergent, cleaner, personal care, or fabric softening applications.
摘要:
The present invention provides a process for easily producing an alkylene oxide adduct to an aliphatic amine compound which has a fully excellent color, is not turbid, and does not deteriorate in color even through long-term storage. That is, the present invention provides a process for producing an alkylene oxide adduct to a primary or secondary amine compound having an aliphatic, saturated or unsaturated, hydrocarbon radical having 8 to 22 carbon atoms, having an excellent color, by reacting an alkyene oxide to the amine compound, characterized by comprising the step of adding a base or an aqueous solution thereof to the amine compound and then heating the mixture.

摘要:
The present invention provides gasoline compositions and gasoline additive concentrates containing compounds of general formula (I), wherein R1 represents a hydrogen atom or an alkyl, aryl or alkaryl group; R2O is a residue of a polyether mono-ol or a hydrocarbyl mono-ol of formula R2OH; and R?3 and R4¿ each represent a hydrogen atom or together represent a carbon-carbon single bond, wherein when R?3 and R4¿ each represent a hydrogen atom, then each of R?5 and R6¿ independently represents a group -CH¿2N(R?7)2 in which each R7 independently represents a hydrogen atom or an optionally substituted alkyl group, and when R?3 and R4¿ together represent a carbon-carbon single bond, then R?5 and R6¿ each represent a cyano group; use of the compounds of formula (I) as gasoline additives for reducing intake valve deposit formation; novel compounds, being compounds of formula (I) above, with the proviso that when R1 is a hydrogen atom or a C¿1?-C4 alkyl group, R?3 and R4¿ together represent a carbon-carbon single bond, and R?5 and R6¿ each represent a cyano group, then R2O is a residue of a polyether mono-ol of formula R2OH; and a process for the preparation of the novel compounds of formula (I).
摘要:
Die Erfindung beschreibt neue sekundäre Polyetherpolyamine, sowie deren Verwendung und Herstellung. Insbesondere werden sekundäre Polyoxypropylendiamine und Polyoxypropylentriamine hinsichtlich ihrer Eigenschaften, Synthese und Anwendungen charakterisiert. Mit dieser Stoffklasse ist der Aufbau einer vollständig polyurethanfreien Polyharnstoff-Verbindung möglich. Dabei führt das Polyoxypropylengerüst zu der gewünschten Flexibilität des Polymers, und die hydrophoben Eigenschaften des Polyoxypropylenkörpers verhindern die Aufnahme von Wasser. Die Amin-Endgruppen ermöglichen wegen ihrer hohen Reaktivität darüber hinaus kurze Reaktionszeiten ohne die Verwendung von Aktivatoren. Dabei läßt die Wahl des Substituenten am Amin-Stickstoff eine Anpassung der Reaktionsgeschwindigkeit dieser Verbindung in weitem Rahmen zu.
