Invention content
The present invention is directed to introduce a kind of raw material to be easy to get, cheap succinic acid substitutes the N- maloyls of succinic anhydride Imines synthetic method, high income.
Goal of the invention to realize the present invention, the present invention provide the following technical solutions:
A kind of N- hydroxysuccinimides preparation method, with succinic acid be raw material, with azanol in the presence of acidulous material Reaction prepares N- hydroxysuccinimides.
The reaction mechanism mechanism of reaction is as follows:
Azanol used in this reaction process should be free azanol, can add to obtain free hydroxylamine in reaction process Enter alkaline matter acquisition, sodium bicarbonate, saleratus, sodium carbonate, potassium carbonate, sodium hydroxide and hydrogen can be selected in alkaline matter used Potassium oxide.Consider that it is that optimal selection, bicarbonate and carbonate were using to select sodium hydroxide from safe to use and economics Great amount of carbon dioxide is released in journey easily causes security risk.
It is preferred that free hydroxylamine can be obtained by hydroxylamine hydrochloride or hydroxyl sulfate and sodium hydroxide reaction.
The molal weight ratio of succinic acid and alkali (sodium hydroxide) is 1 in reaction process:1~1.2, optimal proportion 1:1.05 ~1.1.
The molal weight of succinic acid and azanol ratio is 1 in reaction process:1~1.5, optimal proportion 1:1.2~1.3.
Succinic acid and toluene dosage (mass/volume) are than being 1:1.5~3, generally select 1:2~2.5.
The activity that succinic acid reacts in this method is poorer than succinic anhydride, and the activation energy for reacting required is high, in order to make reaction Smoothly through row, need to use catalyst, catalyst that should select acidic materials during the reaction, and be acidulous material, it cannot Highly acid substance is selected, because highly acid substance generates hydroxylamine salt with azanol reaction first in the reaction system.In reaction process Middle hydroxylamine salt is difficult to be dissociated into free azanol or free hydroxy lamine concentration is too low and cannot or be unfavorable for reacting.And weak acid and hydroxyl The hydroxylamine salt that amine is formed is easy to be dissociated into active free hydroxylamine substance at a certain temperature.
Catalyst is acidulous material in this reaction system, and available acidulous material has phosphorous acid, hypophosphorous acid, boron Acid, niter cake, sodium dihydrogen phosphate, potassium dihydrogen phosphate, potassium acid sulfate, acetic acid, propionic acid, butyric acid, formic acid, etc..
It can be used, can also be used in mixed way with single substance when stating weak acid substance in use.Usage amount control is being reacted Object amount 0.5%--5%, optimum amount are controlled in 2%-2.5%.Use out of range is ineffective.
When using catalyst, weak inorganic acid is more better than organic acid.
Weak acid catalyst effect is carbonyl reaction activity in enhancing succinic acid structure during the reaction, and is accelerated in reaction Dewatering speed, this effect are conducive to nitrogen-atoms in free hydroxylamine and react.
It has a certain amount of water in the reaction process that the present invention is introduced to generate, since the presence of water is to reacting unfavorable, institute It is removed with the water that must be at any time generated reaction in reaction system, life is removed using solvent azeotropy process in reaction process of the present invention Cheng Shui such as selects toluene solvant.It can also select hexahydrotoluene, benzene, hexamethylene, etc..Due to being more toxic for benzene, should use up Amount avoids using.
This reaction is could to be reacted under the conditions of certain temperature, therefore the boiling point of reaction dehydrated solvent is selected to must be over 70 ℃.No more than 180 DEG C, more than 180 DEG C product yields significantly reduce reaction temperature.Optimal reaction temperature should be at 100 DEG C to 150 ℃。
There are two types of feed way in reaction process:
The first feed way be according to certain mass ratio by succinic acid, hydroxylamine salt (hydroxyl sulfate or hydroxylamine hydrochloride), Catalyst such as boric acid, sodium hydroxide, solvent toluene mix, with 130 DEG C of progress dehydrations.Reaction yield 70%, should Yield is slightly lower, and main cause is sodium hydroxide and hydroxylamine salt preferential reaction in the feed way, and it is several that hydroxylamine salt is generated in the short time It is converted to free azanol, azanol is unstable at high temperature causes yield low.
Second of feed way is that succinic acid and sodium hydroxide are now carried out reaction to generate succinic acid sodium salt, later succinic acid Sodium salt, hydroxylamine salt (hydroxyl sulfate or hydroxylamine hydrochloride), catalyst such as boric acid, solvent toluene mix, and are taken off with 130 DEG C Water reacts.Reaction yield 85%.Second of feed way is higher than the product yield that the first feed way is obtained.Main cause It is gradual formation for azanol free during the reaction, rather than is quickly formed in the short time.
Occur without generating water in reaction process, you can illustrate that reaction terminates.Since product does not dissolve in toluene, it is easy into Row is separated by solid-liquid separation.After isolating toluene, remaining solid is dissolved with ethyl alcohol, removes the salt that reaction process generates.Last crude product Use re-crystallizing in ethyl acetate.
