Love Attorney, Agent, or FirmWo0dhams, Blanchard and Flynn [57] ABSTRACT A quaternary ammonium salt containing an ester linkage in the cationic moiety is prepared by reacting an epihalohydrin with a salt of an alkyl or alkenyl tertiary amine and a carboxylic acid.
5 Claims, No Drawings PROCESS FOR THE PREPARATION OF QUATERNARY AMMONIUM SALTS BACKGROUND OF THE INVENTION This invention relates to a new process for preparing quaternary ammonium salts which are useful as detergents, emulsifying agents and wetting agents, particularly as textile treating agents.
DESCRIPTION OF THE PRIOR ART A conventional method of preparing quaternary ammonium salts, which is usually adopted in the art, comprises reacting an alkyl amine with an alkyl halide. Re cently, methods using an epihalohydrin are adopted sometimes. The most typical method using an epihalohydrin comprises reacting an epihalohydrin directly with a tertiary amine. However, in this method it is difficult to prepare quaternary ammonium salts having a complicated structure. It is especially difficult to introduce a reactive group into the cationic moiety.
As disclosed in US. Pat. Nos. 2,547,965 or 2,548,679, it has been known that when an adduct of a tertiary amine with an alkyl phenol or mercaptan synthesized in advance is quaternarized by an epihalohy drin, the alkyl phenol or mercaptan is introduced in the cationic moiety in the form of a phenyl ether or thioether. However, since the linkage introduced into the cationic moiety is an ether linkage, its reactivity is relatively low. Also, a method comprising synthesizing in advance a salt of a tertiary amine with a mineral acid such as hydrochloric acid and then reacting an epihalohydrin with the salt has been known in the art. However, according to this method it is impossible to introduce a reactive group into the cationic moiety.
DETAILED DESCRIPTION This invention is based on the discovery of a process for preparing quaternary ammonium salts having a reactive ester group in the cationic moiety, which are useful as textile-treating agents. The products obtained by the process of this invention are useful as textilesoftening agents having an antistatic property, or as level-dycing or dyeing-retarding agents of the decomposition type.
More specifically, this invention is to provide a process for the preparation of quaternary ammonium salts having an ester linkage in the cationic moiety, characterized by reacting an epihalohydrin with a salt of an alkyl or alkenyl tertiary amine and a carboxylic acid.
The salt of an alkyl tertiary amine and a carboxylic acid may be prepared in an ordinary solvent such as benzene and lower aliphatic alcohols by a customary method. The kind ofthe epihalohydrin is appropriately chosen depending on whether the intended quaternary ammonium salt is a chloride or bromide.
Quaternary ammonium salts to be obtained by the process of the present invention are represented by a chemical formula as follows:
i R1 til ca claca ofi R x' R3 on in which R is an alkyl, alkenyl or cycloalkyl radical of from 1 to 17 carbon atoms; in which N is a quaternary nitrogen atom; in which X is halogen, such as chlorine, bromine and fluorine; and in which each of R,, R and R is an alkyl or alkenyl radical having 1 to 18 carbon atoms.
In the production of these compounds, the following three reactants are used:
I. An alkyl or alkenyl tertiary amine having the formula wherein each of R R and R is an alkyl or alkenyl rad ical having 1 to 18 carbon atoms.
Some examples of alkyl or alkenyl tertiary amines which may be quaternized in the practice ofthe present invention are as follows:
Trimethylamine, triethylamine, trinormalpropylamine, dimethylethylamine, methyldiethylamine, dimethylallylamine, diethylallylamine, dimethyldodecylamine, dimethyloctadecylaminc, trioctylamine, trioctadecylamine and trioleylamine and mixtures thereof.
2. Epihalohydrin, for example, epichlorohydrin or epibromohydrin.
3. A saturated or unsaturated aliphatic carboxylic acid, or alicyclic acid having from 2 to 18 carbon atoms and represented by the formula of RCOOH, wherein R is an alkyl, alkenyl or cycloalkyl radical such as cyclohexyl and adamantyl having from 1 to 17 carbon atoms.
Some examples of carboxylic acids which may be used in the practice of the present invention are as follows:
Acetic acid, lauric acid, crotonic acid, acrylic acid, methacrylic acid, oleic acid, l-adamantyl carboxylic acid and cyclohexyl carboxylic acid.
Our process involves the preparation of a salt of an alkyl or alkenyl tertiary amine and a carboxylic acid by neutralizing the carboxylic acid with the amine in substantially stoichiometric amounts. Then, the salt is re acted with epihalohydrin. The reaction may be carried out at any suitable temperature and pressure, temperatures between 50C and C and pressures at or near atmospheric being suitable. Conveniently, the reaction is carried out in the presence of a solvent such as benzene and a lower aliphatic alcohol, for example, methanol, ethanol, propanol, butanol, pentanol, etc. The temperature of the reaction may be very conveniently controlled by conducting the reaction under reflux conditions. We have found that the use of benzene is highly satisfactory.
Epihalohydrin can be used in a substantially stoichiometric amount, but it may be preferably employed in a slight excess, for example, 20 percent excess over its stoichiometric amount.
After the reaction, the solvent employed is first distilled off. Purification is largely by way of removal of small quantities of unreacted reactants by any suitable means such as extraction with a suitable solvent, for example, diethyl ether and/or recrystallization from a suitable solvent, for example, acetone and diethyl ether.
Our process has outstanding advantages in that the highly desirable quaternary compounds may be we pared in excellent yield and quality, from available and relatively inexpensive raw materials, by a simple method and with the use of conventional equipment.
This invention will now be illustrated more detailedly with reference to Examples.
EXAMPLE 1 25.8 g (0.3 mole) of crotonic acid was dissolved in 150 g of benzene, and the solution was neutralized by addition of 30.4 g (0.3 mole) of triethylamine. Then, 33.4 g (0.36 mole) of epichlorohydrin was added to the solution, and the reaction was conducted at 80C. for 15 hours. After completion of the reaction, benzene was distilled off under reduced pressure and unreacted reactants contained in the residue were removed by extraction with diethyl ether to obtain 50.4 g of a grayish brown, jelly-like product having a structure expressed by the following formula (I):
