Description
Technical field
The present invention relates to a kind of catalyst and preparation method and purposes for synthesizing phosphoric acid extraction defoamer.
Background technology
Since this phosphoric acid extraction defoamer needs the reactant aqueous solution using succinic acid dibasic acid esters and sodium pyrosulfite, the reaction
It is two phase reaction, reaction rate is limited by phase contact area size.Generally use raises temperature and additional phase transfer catalyst
Method.Rise temperature not only easily makes ester hydrolysis, but also sulfonating agent is decomposed aggravation, therefore can cause sulfonating agent loss and sulfonation
Reaction is incomplete.Passing through the method heated under closed system, it is possible to reduce sulfur dioxide escapes and suppresses the decomposition of sulfonating agent,
But the resistance to pressure requirement to reaction unit is so added again.The method of extra catalyst often makes the final product of reaction again
In contained impurity level increase, product quality is impacted.
The content of the invention
The purpose of the invention is to overcome defect and problem existing in the prior art, and provide a kind of synthesis phosphoric acid extraction
The catalyst and preparation method and purposes of defoamer.Catalyst provided by the invention avoids introduced miscellaneous of extra catalyst
Matter so that obtained product purity is high.
The present invention is realized by following technology：
A kind of catalyst for synthesizing phosphoric acid extraction defoamer, each component mass percentage, it is characterised in that the catalysis
Agent is prepared according to the following steps：1) by 40~50% diisooctyl maleates, 5~20% succinic acid di-isooctyl sulfonic acid
Sodium is uniformly mixed；2) 10~15% sodium pyrosulfite is dissolved in spare in 25~35% water；3) temperature for 100~105 DEG C,
Under normal pressure, the sodium metabisulfite solution prepared in step 2) is added drop-wise in the system of step 1) in 1~4h, the reaction was continued 5
~8 it is small when, products therefrom for homogeneous phase transparent liquid be synthesize phosphoric acid extraction defoamer catalyst.
It is just pungent for 30~70% diisooctyl succinate sodium sulfonates or succinic acid two that the catalyst contains mass fraction
Ester sodium sulfonate.
A kind of preparation method for the catalyst for synthesizing phosphoric acid extraction defoamer, each component mass percentage, its feature exist
Carried out according to the following steps：1) 40~50% diisooctyl maleates, 5~20% diisooctyl succinate sodium sulfonates are mixed
Close uniform；2) 10~15% sodium pyrosulfite is dissolved in spare in 25~35% water；3) it is 100~105 DEG C, normal pressure in temperature
Under, the sodium metabisulfite solution prepared in step 2) is added drop-wise in the system of step 1) in 1~4h, it is 5~8 small that the reaction was continued
When, products therefrom as synthesizes the catalyst of phosphoric acid extraction defoamer for the liquid of homogeneous phase transparent.
The aqueous solution that the catalyst of above-mentioned synthesis phosphoric acid extraction defoamer is used for succinic acid dibasic acid esters and sodium pyrosulfite is anti-
Ying Zhong, additive amount account for the 5~20% of succinic acid dibasic acid esters and sodium pyrosulfite total amount.
Catalyst provided by the invention has the features such as Catalysis Rate is fast, is easily obtained, of low cost, and will not introduce
Exogenous impurity, the catalyst not only reduced after reaction remove link, reduce production cost, and high-purity can be made
Phosphoric acid extraction anti-foam product.
