Propine alcohol ethoxylates are used as nickel plating brightener, specifically used method are as follows: in 250~300g/L of nickel sulfate, nickel chloride 50
~60g/L, 40~50g/L of boric acid basal liquid in, be added 1~2g/L of saccharin sodium, add propine alcohol ethoxylate 0.01
~0.03g/L, at 50~60 DEG C, 3~5A/dm of cathode-current density2Under be electroplated.
Compared with prior art, technical solution of the present invention, which has the following beneficial effects:, solves following technical problem:
First technical problem is that preparation method of the present invention not only overcomes traditional inorganic base catalyst color
Problem deep, alkynyl retention rate is low, and it is more environmentally protective.
Such as due to traditional inorganic base catalyst: potassium hydroxide and sodium hydroxide are easy to cause alkynol substance to decompose reduction alkynes
Base retention rate, decomposition while, will lead to color burn, while propilolic alcohol is easy to oxidize under basic conditions that catalyst is made to lose work
Property, cause synthesis to occur dangerous, and the relatively low hot conditions for generally requiring 100 DEG C or more of catalytic activity could be catalyzed well
Synthesis, is unfavorable for the narrow ditribution of ethylene oxide under these conditions.It needs to use distillation decoloration since color is too deep, and distills de-
Color will bring various three wastes problems, more environmentally protective compared to this technique of traditional handicraft.

The problem of purity requirement.Realize one-step synthesis, three-waste free discharge.Traditional handicraft distills bring security risk and waste water, gives up
Slag etc. is difficult to handle, and preparation method of the invention can substitute original mode for needing distilation, substantially reduces waste
Amount.
Traditional catalyst inorganic base and fatty amine catalysate contain a large amount of unreacted third since molecular weight distribution is wider
Alkynol and other by-products, this kind of by-product is unfavorable to nickel plating, while the purity reduction of product will make product without competing
Striving power can not be with same kind of products at abroad to matching in excellence or beauty, and the present invention uses the nitrogenous class catalyst of large space steric hindrance can be with single sintering just
It can achieve with same kind of products at abroad to matching in excellence or beauty, remove distillation technique from, shorten process flow, reduction while having saved energy consumption
Real greenization production has been accomplished in the discharge of waste water and dregs.
4th technical problem is the distribution character of improvement product, improves the narrow ditribution characteristic of product.Improve product
Application effect.
Using the organic alkali quaternary ammonium salt catalyst with steric hindrance due to its space steric effect, can influence to produce
The distribution of epoxy adduct number in product, and then enhance product performance.The alkane with narrow ditribution characteristic supports based compound tool in general
There is more excellent performance, this product is also related with molecular weight distribution width, and relatively narrow properties of product are more excellent.
