'13 Claims. ,(Cl. 160-404) This .Iinventionrelates (to the preparation -.of. new and tuseful .polymerizable :N-acylamido .fatty acid compounds, .--and more-,particularlyto -such .compounds-.1n which the acyl groupiseitheracryl or methacryl. This invent on talso relates to.a=.-new and inexpensive-method for the preparation ofthese useful compounds. I
f It is .an object of this invention -to prepare compounds .that.areuseful in the preparation ofygreases-andsoaps.
It is another object of this invention to produce such compounds as. are susceptible tov polymerizat1on,. thereby to increase themolecular weight of the compounds so that higher melting points 'and altered solubihty are obtained. These properties are of particular usefulness 1n the preparation of greases, but are valued as well in the preparation of thickening agents and stabrhzers.
It'is1also.anobject of this:inventi'on'.-to prepare: N- acyIamidoifattyI acids chea-ply by. the: usevof inexpens ve ireagents andibylisimple procedures wh1ch .can:be.carr1ed toutmat or near roomztemperature andpressure, .thereby permitting the employment :.:of a simple and UZIJGXPBIISIVG equipment.
Theiobjectsfof the instant invention xarerrealizedcby. the
reaction ofzaniacrylo ormethacrylo: nitrile-witlr an :ethylenically I unsaturated 1: and sunconjugated fatty racld, tor a -secondary-tihydroxy fatty-tacid wvhereinathe secondary hyidroxyliradical rdoesanotireside oni. thezralpha' carbon: atom. The reaction is effected in the presence ofi -axconcentrated mineral sacid, this term cbei-ng .used 1 :herein n'n xthe :usual sense to mean such/acids as-sulfuric,. phosphorlc, boron trifluoride and similar acids. Isolation of the product is easily accomplished by drowning of the reaction mixture with water and filter-ing extracting, or otherwise separating the product.
It" has beendiscoveredin accordance with the-*mStant invention *that 'the reaction outl-ine'd above takes place readily when use-is made'offfatty aci'ds 'contammg -an ethylenic unsaturation or dou'ble bond,"either-at theend of the car-bon chain--i-'suoh as wi'thundecylenic aoid--or where the double"bond occursinithetmiddle portion of the chain-such as with oleicacid; but the reaction does not occur where "the unsaturation' is conjugated with the carbonyl group such-as :with acryllc acids, If a .hydroxy fatty .acidis used as the .starting mater1al, ..-the 'lhy'droxy ,group must .be located on .=a.;seco n;dary; carbon .atom,.since it hasbeenfoundthati the reactlon withgprl- .mary. alcohol istooislowito be-of,pract1cal value. The I hydroxyl group .can. not reside on the. alpha. carbon atom, since it .haslbeen found that .alpha-hy'droxyr'stearlc "acid and lactic acid are inoperative. However,'beta-hydroxy acids, such as: beta-hydroxy-caproic react. readily.
Where an ethylenically unsaturated fatty acid is used as a reactant, there 'are generally obta ined simultaneouslya mixture of two products. in .varylng proportions. When the unsaturation resides at .the-end of a;.ca'rbon chain, only'one product'has been Ifoundnamely, the secondary derivative. "Thus only IO N-methacryI-anndoundecylenic acid. In the case of the hydroxy fatty acids, the amino group enters the position previously occup1ed by the hydroxy group used in the starting material.
While mixtures of compounds are usually obtained when an ethylenically unsaturated fatty acid is used as a reactant, it has been found that such mixtures are not a disadvantage, but that they can be readily used together since the properties of the isomers are so similar. The isomers can be separated if desired by standard techniques such as chromatography.
. undecylenic acid is obtained from methacrylo-nitrile and The reaction desired. herein is not limited in .scope .by
.thelength of the fatty acidcarbon chain. "However, it .has -been. .found .that.'.fatty acids .containing between .11 131K122. carbon. atoms. react .to,.giveproducts whose proper- .tiesaretespecially desirable, and which-products are with- .in -.the .scope of the instant .invention.
[It has'been furtherfound that the react-ion is not limited '.t0 .the fatty acids alone,'but proceeds equally well with their derivatives. "The presence of impurities in the .starting materials,.such.as saturated fatty. acids, in no way detracts from .theelfectiveness of the instant invention.
simplifies gpurification. Following purlfication .of the grodugt, the polymer may readily be formed .therefrom' if esire The'manner ofaddition of the 'reagents'is not critical. -Any ":one :can be added to "-a' solution of the other two. 'Howeverfth'e addition of the-mineralacid to atsolutio'n .of the organic'reactants; is preferred.
The acrylamidoan'cl methacrylamido fatty :'acids and derivatives thereof; prepared herein can be polymerizedto molecules of higher'molecular-weightbythe use of 'high temperatures "or the ;use i of peroxide catalysts such :as "benzoyl peroxide. The products of 'such polymerization 'haveproper'ties useful in theproduction. of alkyd resins, greases, fstabillzers, and. similar compounds.
