Abstract
The present invention relates to a preparation method for surface active agents from lignosulphonates; in the present invention, alkyl halides are adopted as an analkylation reagent for introducing alkyl chains to the molecules of the lignosulphonates. An alkylation method for the present invention comprises the following steps; firstly, the pH value of a lignosulphonate solution is regulated to 10 to 12, and linear alkyl halides containing 8 to 16 carbon atoms and accounting for 20 to 40% of the weight of the lignosulphonates are added to the solution; then, the solution is heated to 130 to 170 DEG C after being sealed, and cooling and material discharging are finally carried out after reactions are carried out for 1 to 3 hours. The alkylated lignosulphonates prepared by the present invention have the advantages of better amphipathy and greatly enhanced surface activity, and have high dissolvability both in water and oil.
Description
The present invention relates to a kind of method for preparing tensio-active agent with sulfonated lignin.
Xylogen is one of main component in the plant fiber material.In pulp and paper industry, the lignin dissolution in the plant fiber material forms sulfonated lignin or alkali lignin in cooking liquor.These two kinds of important by-products that industrial lignin is a pulp and paper industry, at present also very insufficient to their utilization.Industrial lignin has many-sided character such as dispersion, bonding and surfactivity, now as dispersion agent, cement water reducing agent, tackiness agent, also can be used for sacrifice agent that tensio-active agent recovers the oil etc.But the xylogen surfactivity is relatively poor, still can not be used alone as tensio-active agent.If wish they are made tensio-active agent efficiently, also need pass through a series of chemical modification.For example, be that raw material carries out sulfomethylation with the alkali lignin, introduce hydrophilic sulfonic group and lipophilic methyl, increase hydrophilic and oleophilic functional group, can make alkali lignin have certain surfactivity, but such modification is quite limited to improving the surfactivity role.Contain hydrophilic sulfonic group, lipophilic phenyl ring and alkyl group side chain on the lignosulfonic acid molecules of salt, therefore surfactivity is higher than alkali lignin, but because intramolecularly lacks the more regular lipophilic group of structure, so surfactivity is still relatively poor, can only become complexed surfactant with other surfactant compound usually.For example, Kalfoglou etc. mix use with sulfonated lignin with alkylbenzene sulfonate etc., can reduce the consumption of alkylbenzene in the surfactant system.But in complexed surfactant, sulfonated lignin can only play the effect of cosurfactant, reduce surface tension and interfacial tension effect significantly and play, and mainly are still synthetic surfactants such as sulfonated petro-leum.
Sulfonated lignin are carried out alkylation, can strengthen and improve its surfactivity.Early the useful methyl-sulfate of alkylation that uses methylates, or methylates with diazomethane.The alkyl carbon chain that but this method is introduced is very short, and can't play increases the oil loving effect of sulfonated lignin, and the agents useful for same costliness, and severe reaction conditions does not possess practical value.People such as Meister introduce alkyl chain with sulfonated lignin and vinyl monomer copolymerization to lignin molecule, can increase the lipophilicity (the 3457th page of J.Appl.Polym.Sci.1984 the 29th volume) of sulfonated lignin.But other for example makes sulfonated lignin and propylene oxide copolymerization to the method for xylogen introducing side chain, then can not increase the surfactivity of xylogen, but xylogen is made the prepolymer (J.Appl.Polym.Sci. of engineering plastics, 1984,29 volumes, 1113 pages).
The purpose of this invention is to provide and a kind ofly prepare the method for tensio-active agent,, increase substantially its surfactivity by sulfonated lignin are carried out chemical modification with sulfonated lignin.
The present invention is alkylating reagent with the halogenated alkane, introduces long alkyl chain on the lignosulfonic acid molecules of salt.The alkylating method of sulfonated lignin is: sulfonated lignin are dissolved in the water, regulate pH value to 10～12 with alkali, add the halo straight-chain paraffin that contains 8～16 carbon atoms that accounts for sulfonated lignin weight 20%～40%, the sealing post-heating, be warming up to 130～170 ℃, naturally cooling discharging behind reaction 1～3h.
Used sulfonated lignin are generally sodium lignosulfonate or calcium lignosulfonate, and the former is better than the latter at performance.
Halohydrocarbon is the halo straight-chain paraffin that contains 8～16 carbon atoms, wherein preferably contains the bromo straight-chain paraffin of 12～16 carbon atoms.Though the alkane iodide reactive behavior is higher, higher because of cost, should not use.Though branched paraffin can react with sulfonated lignin, the surface tension of product water solution is higher, therefore is not suitable for preparing tensio-active agent.
The alkylation sulfonated lignin made from the present invention have amphipathic preferably, very high solubleness is all arranged in water and oil, and surfactivity strengthen greatly.At room temperature, the surface tension of the alkylation surfactant soln of 1% weight percentage can be reduced to 36mN/m, and the interfacial tension between this solution and the oil can reduce to 10
-3MN/m.
Can directly use through the sulfonated lignin behind the alkylation modification, also can use, to obtain better to reduce the effect of oil water interfacial tension with other tensio-active agents are collaborative as the major surfaces promoting agent.This tensio-active agent is used for tertiary oil recovery, can use separately, also can be used with alkali, polymkeric substance etc., plays the effect of the recovery ratio that improves crude oil.
