Embodiment Construction

[0021] 1. Preparation of supported catalyst

[0022] The supported catalyst can use any one or a mixture of two or more of nickel nitrate, copper nitrate, cobalt nitrate, chromium nitrate, and lanthanum nitrate, and add any one or two or more of cerium oxide, ammonium molybdate, and ammonium rhenate The mixture was dissolved in distilled water, stirred while heating until completely dissolved, and then transferred to a petri dish. In the mixture of two or more kinds of nickel nitrate, copper nitrate, cobalt nitrate, chromium nitrate and lanthanum nitrate, the ratio of each component can be adjusted at will. In the mixture of more than two kinds of cerium oxide, ammonium molybdate and ammonium rhenate, the ratio of each component can also be adjusted at will.

[0023] 45 g of the pre-dried silicon dioxide and aluminum oxide mixed carrier were uniformly placed in the above-mentioned petri dish, ultrasonically oscillated for 15 minutes with an ultrasonic cleaner, and then tran...

Abstract

The invention discloses polyether amine for a textile printing and dyeing auxiliary and a preparation method. The preparation method includes: adding trimethylolpropane serving as initiator and catalyst KOH (potassium hydroxide) into a reaction kettle, and sequentially feeding epoxyethane and epoxypropane into the reaction kettle so that a polyether crude product is prepared by means of reaction; neutralizing and adsorbing the reactant prior to filtering dehydration, and then refining through reduced pressure distillation and dehydration so that polyether is prepared; and adding the prepared polyether, supported catalyst, liquid ammonia and hydrogen so that the polyether amine for the textile printing and dyeing auxiliary is prepared. The polyether amine serves as a textile printing and dyeing softener, demulsification temperature of emulsion is high, polyether consumption is less, and total production cost can be reduced. The polyether amine prepared by the preparation method is high in amino terminating ratio, equimolar consumption of a main system is reduced, system viscosity is increased, and produced textiles are integrally softer in hand feeling. Besides, the preparation method is less in reaction by-products, loose in reaction condition, low in equipment requirements and small in equipment investment.

Description

[0001] technical field [0002] The invention relates to a polymer organic amine compound, in particular to polyether amine as the main component used in the preparation of textile printing and dyeing auxiliary softener and its preparation method. Background technique [0003] Polyetheramine is a compound that converts the hydroxyl value at the end of polyether polyols into amino groups. It is widely used as a raw material for epoxy resin curing agents, spray polyurea and hydrogel products. In the applicant's search, there is no report of polyetheramine used as textile printing and dyeing auxiliary softener. [0004] There are two types of methods for preparing polyetheramines: leaving group method and catalytic amination method. Among them, the leaving group method has many synthesis steps, many reaction by-products, and relatively difficult separation. Therefore, generally domestic and foreign industrial production Both are based on catalytic amination method. However, th...
