Abstract
The present invention discloses a preparation method of a leveling agent, comprising the steps of: (1) feeding; (2) adding a catalyst; (3) adding EO for reaction; (4) post-processing; and (5) pressing, cooling and cutting into slices. Compared with the conventional preparation processes, the preparation method is higher in yield and less in process procedures.
Description
Technical field
The present invention is specifically related to a kind of preparation method of levelling agent.
Background technology
Levelling agent be fabric in dyeing course, for impelling even dyeing, do not produce the fault such as vitta, color spot and the material that adds, and the operation that general levelling agent preparation method needs is more, and output is not ideal enough.
Summary of the invention
Goal of the invention: the present invention provides the preparation method of the high levelling agent of a kind of production efficiency in order to solve the deficiencies in the prior art.
Technical scheme: for achieving the above object, the technical solution used in the present invention is as follows: a kind of preparation method of levelling agent, described preparation method comprises the following steps:
(1) feed intake: C16 ~ 18 alcohol are dropped into the stirring-type crucible, are to react 6-10h in 90-110 ℃ in temperature, are molten into liquid; (2) add catalyzer: the liquid negative pressure suction reactor with making in the step (1), add conventional basic catalyst, be warming up to 100-120 ℃, simultaneously negative pressure dehydration 40-60min;
(3) add EO reaction: at the 150-170 ℃ of lower EO reaction 4-6h that slowly adds, and pressure-controlling that will this moment drops to normal pressure with pressure after the reaction 30-60min, control during sampling is surveyed more than 0.4 MPa;
(4) aftertreatment: middle control data reach after the cloud point, cool to 120-130 ℃, add in the conventional acid and 10-30min, cool to 110-120 ℃, add discoloring agent again and process 10-30min;
(5) binder, cooling section: carry out binder after cooling to 90-110 ℃ and in reactor, cut into slices, last packing.As preferably, the mass ratio of described C16 ~ 18 pure and mild EO is 200-300:1000-1300.
As preferably, in the step (4), described cloud point is 91-94 ℃.
Beneficial effect: compared with prior art, operation is few, and output is higher.
