Abstract
The present invention relates to a chelating surface active agent which belongs to the technical field of fine chemical industry. The chemical structural formula of the chelating surface active agent is the right formula, wherein X2=O, R2=H, X1=O or N, and R1=an aliphatic radical; X1=O, R1=H, X2=O or N, and R2=an aliphatic radical. The surface active agent simultaneously has strong surface activity and strong chelating capability; when the surface active agent is matched with other surface active agents, the salt resistance and the hard water resistance of a mixing system can be obviously enhanced.
Description
Technical field:
The invention belongs to the fine chemical technology field, relate to a kind of surfactant.
Background technology:
Chelate surfactant, claim chelate surfactant again, wherein studying more is EDTA derivative class surfactant, but its production technology more complicated, use the cyanide of severe toxicity in most production processes again, and the degradability of EDTA itself is being under suspicion recently again.
Summary of the invention:
The technical problem to be solved in the present invention is to disclose a kind of degradable chelate surfactant.
Chelate surfactant provided by the invention is reacted in the presence of catalyst by imino-diacetic butanedioic acid and fatty alcohol or fatty amine and obtains.
Iminobisuccinate derivative class surfactant structure general formula of the present invention is:
X wherein
2=O, R
2=H, X
1=O or N, R
1=aliphatic group;
Perhaps X wherein
1=O, R
1=H, X
2=O or N, R
2=aliphatic group.The aliphatic group carbon atom quantity can be 1 to 30 carbon.
The degradable chelate surfactant that the present invention produces is realized by following steps:
Imino-diacetic butanedioic acid and fatty alcohol or fatty amine can directly react in the presence of catalyst, and this reaction is a reversible reaction, by constantly distilling out or carry out the water that reaction generates, molecular balance are moved to the direction that generates product, improve product yield.This catalyst for reaction is the strong acid compound, adopts sulfuric acid, sulfonic acid etc. usually, and recent development trend is to adopt zeolite molecular sieve, heteropoly acid, solid super-strong acid or strong-acid ion exchange resin, and relevant monograph is more.
Iminobisuccinate derivative class surfactant provided by the invention is a kind of novel surfactant, and chelate surfactant has very strong surface-active and sequestering power simultaneously; During with other surfactant compatibilities, can obviously improve the salt tolerance and the anti-hard water of mixed system; Be suitable for preparing without phosphorus, hyperconcetration heavy-dirty liquid-detergent; Under acid condition, can reduce the corrosion rate of steel, under alkali condition, can make the steel surface passivation and play a protective role, therefore have broad application prospects.And production equipment is simple, and condition control is easy, and technological process is short.
The specific embodiment:
1, synthetic imino-diacetic butanedioic acid single lauryl alcohol ester
Adopt a whole set of Soxhlet extraction element as reaction unit.600 milliliters of dry imino-diacetic butanedioic acid 24.9 grams (0.1 mole), laruyl alcohol 18.6 grams (0.1 mole), 0.5 milliliter in sulfuric acid and solvent dimethyl formamides are housed in the flask.Restrain with filter paper barreled anhydrous magnesium sulfate 100 in the extractor, with the water of taking out of in the absorption reaction system.Agitating heating back flow reaction 15 hours stops.Mixture in the flask is carried out decompression distillation, reclaim most of solvent, about 480 milliliters of dimethyl formamides, residue cooling is poured in 1 liter the cold water, generates precipitation, the agitator treating sediment filters collecting precipitation, and sediment is poured in 1 liter 0.01 mole the sodium bicarbonate solution, agitator treating, filter, wash sediment again with water, sediment is dry under vacuum, 40-50 ℃ condition, obtain product, yield 76%.
2, synthetic imino-diacetic mono succinate acyl lauryl amine
Method of operating is the same, but replaces laruyl alcohol, product yield 79% with 18.5 gram (0.1 mole) lauryl amines.
Claims (2)
1, a kind of chelate surfactant is characterized in that having following chemical structural formula:
X wherein
2=O, R
2=H, X
1=O or N, R
1=aliphatic group;
Perhaps X wherein
1=O, R
1=H, X
2=O or N, R
2=aliphatic group.
2, chelate surfactant according to claim 1 is characterized in that: the aliphatic group carbon atom quantity is 1 to 30 carbon.
