Description
Technical field
The present invention relates to the preparation method of a kind of BDO gemini di-sec-octyl succinate sodium sulfonate.
Background technology
BDO gemini di-sec-octyl succinate sodium sulfonate is to design strand surfactant sulfo group in the molecule
Succinic acid Zhong Xin ester sodium salt, as the ion head of parents' molecule, is formed by connecting by chemical bond through linking group BDO
Gemini surface active agent.Its surface activity, in addition to all advantages with strand surfactant, also has lower surface
The most higher surface activity of tension force.Owing to its special structural table reveals the performance of uniqueness, thus it is more widely applied.With Isosorbide-5-Nitrae-
Butanediol, maleic anhydride and sec-octyl alcohol are that BDO gemini di-sec-octyl succinate sodium sulfonate prepared by raw material, this product
Report without document before items.
Summary of the invention
It is an object of the invention to provide a kind of easy operation, the BDO Shuangzi succinum that method is easy, the feature of environmental protection is good
The preparation method of acid di-sec-octyl sodium sulfonate.
The technical solution of the present invention is:
The preparation method of a kind of BDO gemini di-sec-octyl succinate sodium sulfonate, is characterized in that: include following step
Rapid: maleic anhydride and two hydroxy combinings on BDO carry out single-esterification and generate the double maleic acid list of BDO
Ester, the double maleic mono-ester of BDO carries out double esterification reaction again with sec-octyl alcohol, and to obtain the double maleic acid di-secondary of BDO pungent
Ester, the double maleic acid di-sec-octyl of last BDO carries out conjugate addition sulfonating reaction with sodium sulfite again and prepares product;
Wherein, the catalyst of double esterification reaction is carbon-based solid acid catalyst.
During single-esterification, maleic anhydride and BDO mol ratio are 2.15:1.0.
During double esterification reaction, sec-octyl alcohol addition is 1.00 1.05 by the mol ratio of maleic anhydride Yu sec-octyl alcohol.
During sulfonating reaction, the consumption of sodium sulfite presses maleic anhydride and NaHSO3Mol ratio be 1.00 1.05.
Reaction equation:
The present invention easily operates, method easy, the feature of environmental protection is good.
1, BDO gemini di-sec-octyl succinate sodium sulfonate is a kind of new Gemini surface active agent, currently without
Directly related document was reported.
2, the present invention uses carbon-based solid acid (the immobilized p-methyl benzenesulfonic acid of starch) to make catalyst for esterification reaction, catalyst manufacture
Simply, cheap, and esterification products only need to be carried out simple filtration just can separating catalyst, the catalyst of separation is repeatable
Use.Avoiding liquid acid catalyst to be difficult to separate with product, etching apparatus, the catalyst such as metal solid is sour make trouble and valency
The shortcomings such as lattice are high.
3, this technique need not when double esterification reaction additional make water entrainer and double esterification reaction often such as toluene equal solvent
Pressure carries out being esterified dehydration.Avoiding existing Shuangzi sulphosuccinates of preparing needs additional water entrainer maybe to need to use decompression
The method of dehydration, decreases the requirement to equipment of reducing pressure, the consumption decreasing raw material and distillation except the operation of toluene.
4, this technique is when esterification, directly ethylene glycol and cis-butenedioic anhydride is reacted, is not required to added acetone etc. and makees cosolvent, keep away
Having exempted from original technique needs added acetone to make cosolvent, needs distillation except the work of acetone at the end of decreasing the consumption of raw material and reaction
Sequence, it also avoid environmental pollution.
5, the single, double reaction time of esterification of the present invention is short, has effectively contained the phenomenon that double ester hydrolysis and product color are deepened.
6, the most additional phase transfer catalyst of sulfonating reaction, utilizes and controls double esterification reaction esterification yield, by double esterification reaction
Monoesters in become salt as phase transfer catalyst.Decrease the impurity of product and the utilization rate of equipment.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
