Abstract

The invention provides a novel sodium salt cardanol surfactant, which has the following structural formula, wherein R represents C15H31. The invention also provides a preparation method for the novel sodium salt cardanol surfactant. High-purity cardanol extracted from natural cashew nut shells is innocuous and light in color; and the innocuous environment-friendly novel cardanol surfactant with excellent performance can be obtained by sulfonation reaction of the regenerative biomass cardanol and alkali neutralization. Meanwhile, the novel sodium salt cardanol surfactant has the advantages of good hydraulic lubricating property, strong detergency, moderate foam, good dissolution, low skin irritation, good biodegradability and good compatibility with other surfactants.

Description

A kind of novel sodium salt cardanol surfactant and preparation method thereof
Technical field:
The present invention relates to chemical field, relate in particular to a kind of organic compound and preparation method thereof, particularly a kind of novel sodium salt cardanol surfactant and preparation method thereof.
Background technology:
The application of surfactant is very extensive, various civilian and industrial circles have been deep into, surfactant is parents' compounds, have at least a group significantly polar surfaces to be had compatibility in its molecule, can guarantee the dissolubility in water, another group does not have affinity to water, and has oleophilic properties.Common surfactant hydrophilic group is polar group such as carboxylic acid group, sulfonic group, sulfate, phosphate, amine salt, quaternary ammonium salt, oxygen ethene etc., and lipophilic group is nonpolar hydrocarbon chain.The primary raw material source of lipophilic group is two big classes, the one, and mineral matter (fossil) resource mainly refers to petroleum resources; The 2nd, reproducible biomass resource is meant by vegetable oil, animal oil.At present, in global surfactant market, the oil basic product accounts for 75%, is that the product of raw material occupies the market more than 80% with the petroleum base in China.Be aspect the raw material with the oil, along with oil price goes up gradually, people's environmental consciousness strengthens day by day, and sustainable development impels people to use reproducible natural resources more; Yet aspect living resources, animal oil production capacity is limited, is difficult to satisfy the demand in market, and the performance of excellence such as vegetable oil is renewable with it, non-environmental-pollution and production technology are simple is subjected to people's favor.Surfactant structure of the present invention is similar to sodium n-alkylbenzenesulfonate, and sodium n-alkylbenzenesulfonate, plays an important role in the surfactant field as processability, compatibility and excellent biodegradability etc. in decades because of its good performance always.
Summary of the invention:
The object of the present invention is to provide a kind of novel sodium salt cardanol surfactant and preparation method thereof, described this novel sodium salt cardanol surfactant and preparation method thereof will solve surfactant processed complex of the prior art, compatibility poor performance, non-biodegradable technical problem.
The invention provides a kind of novel sodium salt cardanol surfactant, have following structural formula:

Wherein, R represents C 15H 31
The present invention also provides the preparation method of above-mentioned novel sodium salt cardanol surfactant, utilizes the reaction of anacardol and sulfonated reagent, again with the alkali that contains sodium ion in and back preparation anacardol novel surfactant, the equation of its reaction is as follows:
Figure B2009100522392D0000022
Further, earlier anacardol is added in the reactor during reaction, and then add the sulfonated reagent reaction, wherein, the mol ratio of anacardol and sulfonated reagent 1: 0.8~1.2, transferring product P H value with the alkali that contains sodium ion after the discharging is alkalescence, filters and just obtains described anacardol novel surfactant.
Further, in the material that adds, described anacardol purity is more than or equal to 80%.
Further, in the material that adds, described sulfonated reagent is selected from SO 3, or sulfuric acid (is the green vitriol wet goods as mass fraction 98% sulfuric acid, mass fraction 92.5% sulfuric acid) or oleum (contain mass fraction 20%~25% or 60%~65% free SO 3Sulfuric acid) or chlorosulfonic acid in any one.
Further, in the material that adds, the described alkali that contains sodium ion is selected from NaOH or Na 2CO 3, or NaHCO 3In any one.
Among the present invention, the high purity cardanol that extracts from natural cashew nut shell is nontoxic, look shallow, with this good renewable biomass anacardol process sulfonating reaction, can obtain the anacardol novel surfactant of asepsis environment-protecting, excellent performance again with the alkali neutralization, its mechanism is: generation contained direct-connected phenolsulfonic acid after the hydrogen atom on the phenol ring in the anacardol structure was sulfonated the reagent sulfonation, obtained corresponding sodium salts with the alkali lye neutralization again.

The present invention contrasts in existing existing associated straight chain surfactant, and its effect is actively with tangible.Anacardol novel surfactant production technology of the present invention is easy, can react under normal temperature, the normal pressure, production equipment is less demanding, anacardol novel surfactant of the present invention has good waterpower lubricity simultaneously, strong detergency, moderate foam, dissolubility is good, the skin irritatin row is little, and biological degradability is good; And can be good with the compatibility of other surfactants.Can be widely used in fields such as industrial production and bioengineering as softening agent, washing synergist, emulsifying agent etc.
The specific embodiment:
The invention provides a kind of novel sodium salt cardanol surfactant, have following structural formula:
Figure B2009100522392D0000032
Wherein, R represents C 15H 31
The present invention also provides the preparation method of above-mentioned novel sodium salt cardanol surfactant, utilizes the reaction of anacardol and sulfonated reagent, again with the alkali that contains sodium ion in and back preparation anacardol novel surfactant, the equation of its reaction is as follows:
Figure B2009100522392D0000033
Further, earlier anacardol is added in the reactor during reaction, and then add the sulfonated reagent reaction, wherein, the mol ratio of anacardol and sulfonated reagent 1: 0.8~1.2, transferring product P H value with the alkali that contains sodium ion after the discharging is alkalescence, filters and just obtains described anacardol novel surfactant.
Further, in the material that adds, described anacardol purity is more than or equal to 80%.
Further, in the material that adds, described sulfonated reagent is selected from SO 3, or sulfuric acid (is the green vitriol wet goods as mass fraction 98% sulfuric acid, mass fraction 92.5% sulfuric acid) or oleum (contain mass fraction 20%~25% or 60%~65% free SO 3Sulfuric acid) or chlorosulfonic acid in any one.
