The present invention relates to a novel aspartic acid derivative, a method for producing the same, and a surfactant containing the same as an active ingredient. BACKGROUND ART Conventionally, liquid detergents such as kitchen detergents and shampoos have been used that have sodium alkylbenzene sulfonate as the main ingredient and have added a builder such as sodium tripolyphosphate to increase their cleaning power. However, sodium alkylbenzene sulfonate is highly irritating to the skin, causing problems such as roughness of hands, and furthermore, sodium tripolyphosphate used as a builder has caused environmental pollution problems such as eutrophication of lakes and marshes due to phosphorus. Therefore, in liquid detergents, the main ingredients are being replaced by highly safe surfactants such as sodium lauryl sulfate, α-olefin sulfonate, and alkyl ether sulfate.
However, these surfactants alone do not provide satisfactory detergency and foaming, so fatty acid alkylolamides and amine oxide surfactants, for example, are added as auxiliary agents to enhance detergency and foaming. . However, while fatty acid alkylolamides cause little irritation to the skin and are highly safe, they have a weak detergency-enhancing effect and are unsatisfactory in terms of performance. In addition, amine oxide surfactants have excellent cleaning power and foaming enhancement effects, but they are highly irritating to the skin and eye mucous membranes, and have safety issues.
The reality is that there is a strong demand for auxiliary agents for liquid detergents that are both safe and satisfactory. Therefore, the present inventor developed sodium lauryl sulfate, polyoxyethylene lauryl ether sulfate,
As a result of extensive research into compounds that enhance the detergency and foaming of surfactants used as main ingredients in liquid detergents such as α-olefin sulfonate, we found that an aspartic acid derivative represented by the following general formula met our objective. The present invention was completed after it was found to be highly safe with almost no irritation to the skin or eye mucous membranes. (However, in the formula, R 1 is an alkyl group or alkenyl group having 8 to 18 carbon atoms, and R 2 and R 3 independently represent a hydrogen atom, a methyl group, or a hydroxyethyl group.) Here, by R 1 Number of carbons shown is 8-
The alkyl group or alkenyl group of 18 may be linear or branched, for example, n-
Octyl group, n-decyl group, n-dodecyl group, myristyl group, cetyl group, 2-ethylhexyl group,
Examples include isostearyl group, stearyl group, and oleyl group. The aspartic acid derivative represented by the above general formula is a new substance and is a maleic anhydride compound with the general formula R 2 R 3 NH [However, in the formula, R 2 and R 3 independently represent a hydrogen atom, a methyl group, or a hydroxyethyl group] By reacting with the amine shown in the general formula [However, in the formula, R 2 and R 3 have the same meanings as above] A compound represented by the formula R 1 NH 2 [However, in the formula, R 1 is an alkyl group having 8 to 18 carbon atoms or It can be easily produced and obtained by reacting with a higher aliphatic amine represented by [representing an alkenyl group]. The reaction of the present invention can be expressed as follows. That is, the method of the present invention involves a two-step reaction consisting of an acylation reaction of NHR 2 R 3 with maleic anhydride to produce an intermediate ('), and a Michael addition reaction of the intermediate with R 1 NH 2 . It is carried out by. Both the first-stage acylation reaction and the second-stage Michael addition reaction can be performed without solvent, but
It is usually convenient to carry out the reaction in a solvent. Suitable solvents include aromatic hydrocarbons such as benzene, toluene, and xylene, aliphatic hydrocarbons such as hexane and heptane, alcohols such as methanol and ethanol, nitriles such as acetonitrile and propionitrile, and mixed solvents thereof. etc.
Note that a mixed solvent of the above solvent and water may be used within a range that does not inhibit the reaction. Since the production of intermediate (') by the first-stage acylation reaction can be easily confirmed by infrared absorption spectrum, once the production reaction of intermediate (') is completed, the intermediate is isolated, Alternatively, the next step of Michael addition reaction is performed without isolation. In the acylation reaction, in order to suppress the Michael addition reaction between the intermediate (') once generated and the raw material amine R 1 R 2 NH, maleic anhydride and the amine are
It is preferable to use HNR 2 R 3 in an equimolar ratio at 60°C or lower. Especially when a mixed solvent with alcohol or water is used as the reaction solvent, in order to suppress esterification and hydrolysis of maleic anhydride, The temperature is preferably 20°C or lower. On the other hand, in the Michael addition reaction, it is preferable to use higher aliphatic amine R 1 NH 2 in an equimolar amount to the maleic anhydride used at the beginning of the reaction, and to carry out the reaction at 50°C to 130°C. After the reaction is complete, if the target product is precipitated in the reaction solution, it can be isolated by filtration, but if the reaction yield is high, the target product can be obtained by directly concentrating to dryness. Can be done. If further purification of the target product is required, it may be recrystallized from a suitable solvent such as alcohol or acetone. The aspartic acid derivatives obtained according to the present invention may be used in the form of inorganic metal salts, inorganic acid salts or organic acid salts, and for producing these salts, Li,
Hydroxides or chlorides of Na, K, Ca, Mg, Ba, Zn, Al, inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid,
An organic acid such as acetic acid or p-toluenesulfonic acid may be used. Melting points, elemental analysis values, IR,
