Definitions
- This invention pertains to the preparation of es ⁇ ters via the addition of carboxylic acids to olefini- cally unsat rated hydrocarbons and in particular to the use of perfluorosulfonic acid resins as catalysts.
- Esters in general are highly useful chemicals which have found application in a diversity of uses.
- Acetate esters are used in large quantities as solvents for coatings.
- Acrylate and ethacrylate esters have been used for the synthesis of latex paints, photocurable resins, powder coatings and many other useful products.
- Esters are conventionally made by the reaction of alcohols with carboxylic acids in the presence of a strong acid catalyst to form ester and water. Although the yield of this reaction is normally high, the forma- tion of water represents an inefficiency in the con ⁇ version of raw materials into useful products. Further ⁇ more, the water formed must be purified before it can be discharged into the environment. These limitations have a negative effect on the economics of ester pro- duction. There is therefore a need for a more effici ⁇ ent means of producing esters.
- a method of preparing esters satisfying the above requirements comprises contacting an organic carboxylic acid having 1 to 18 carbon atoms with an ethylenically unsaturated hydrocarbon having 2 to 16 carbon atoms in a mole ratio of carboxylic acid to unsaturated hydrocarbon of from 10:1 to 1:20 at
- ' BU a temperature of 0°C. to 220°C. at a pressure of 0 psig to 5000 psig in the presence of a catalytic amount of a perfluorosulfonic acid resin which is a copolymer of tetrafluoroethylene and a sulfonyl fluoride vinyl ether that has been saponified with caustic and then converted to the acid form.
- a perfluorosulfonic acid resin which is a copolymer of tetrafluoroethylene and a sulfonyl fluoride vinyl ether that has been saponified with caustic and then converted to the acid form.
- reaction temperature may vary widely from 0°C. to 220°C, preferred temperature ranges depend upon the particular ethylenically un- saturated hydrocarbon being used.
- the reaction temperature is preferably between 0°C. and 25°C.
- ethylenically un ⁇ saturated hydrocarbons such as, ethylene, propylene, 1-butene, 2-butene, t-butylene, norbornylene, or cyclo ⁇ hexene higher temperatures may be used.
- the particular temperature required for the optimum reaction conditions varies with the reaction temperature. As a rule of thumb, it is preferable to have the pressure high enough to keep the ethylenically unsaturated hydrocarbon dissolved in the acid or acid ester solution.
- the ethylenically unsaturated hydrocarbons used in the method of this invention are preferably monoun- saturated but do not have to be single components and so may be used as mixtures.
- BAV gas is a convention used in the refining and gas in ⁇ dustry for butadiene absorber vent gas which generally contains from 40% to 20% isobutylene mixed with 40 to 60% normal butenes, principally 1- and 2-butene.
- gas mixtures such as, BAV gas
- the acids which are most suitable for this reaction are formic, acetic, propionic, and higher saturated aliphatic acids; diprotic acids, such as, oxalic, malonic, succinic, glutaric, or adipic, as well as unsaturated acids, such as, acrylic acid, methacrylic acid and crotonic acid.
- diprotic acids such as, oxalic, malonic, succinic, glutaric, or adipic
- unsaturated acids such as, acrylic acid, methacrylic acid and crotonic acid.
- Aromatic acids can also be used, such as, benzoic or phthalic.
- perfluorosulfonic acid resins used as cata- lysts in this invention are commercially available under the Trademark Nafion from the duPont de Nemours Company of Wilmington, Delaware. Suitable variations of these resins are described in U.S. 4,065,512 and in duPont “Innovation", Volume 4, No. 3, Spring 1973.
- catalytic amount of perfluorosulfonic acid resin is meant to mean concentrations, based on the total reaction mixture, of 0.001%, to 5% by weight.
- perfluoro ⁇ sulfonic acid resins were more active, giving higher yields and less by-products, than conventional ion ex ⁇ change resins, such as those provided by Dow, e.g., Dowex 50W-X8, and those from Rohm and Haas, such as the Amberlyst series of resins.
- conventional ion ex ⁇ change resins such as those provided by Dow, e.g., Dowex 50W-X8, and those from Rohm and Haas, such as the Amberlyst series of resins.
- These are strong acid cation exchange resins composed of sulfonated styrene-divinylbenezene beads in macroreticular form.
- These prior art macroreticular resins are rigid, break down under agitation encountered during their use as catalysts and eventually deteriorate in physical form to a powder.
- the Nafion resins on the other hand are extremely resilient.
- Nafion catalysts are ideally suited for use as esterification catalysts in a fluidi- zed bed type of reactor. As polymer supported catalysts, Nafion is also well suited for use in packed bed reactors.
- esters available from unsaturated acids through this invention are polymerizable monomers easily convertible to polymers which are particularly useful in industrial coating and adhesive applications.
- the invention is further described in the examples which follow. All parts and percentages are by weight unless otherwise specified.
- Example 3 was repeated with the exception that the reactor was charged with 16 grams of an equimolar norbornylene/acrylic acid solution and 0.31 grams of Nafion 811 resin instead of the Amberlyst XN-1005. The temperature was raised to 102°C. After 15 minutes the solution was analyzed and indicated a 97% content of norbornyl acrylate. This demonstrates the superiority of the Nafion catalyst over that of an Amberlyst type catalyst.
- Example 5
- Example 3 Reactor used in Example 3 was charged with 16 grams of an equi olar norbornylene/acrylic acid solution and 0.31 grams of dried Dowex 50W-X8 ion exchange resin (a sulfonated styrene-divinylbenezene copolymer obtained from Dow Chemical Company. It is a macroreticular resin.). The temperature was raised to 102°C. Samples were taken and analyzed as follows:
- Example 2 The reactor used in Example 2 was charged with 100 grams of propionic acid, 100 grams of tetrahydro ⁇ furan, 132 grams of isobutylene, and 5.0 grams of Nafion 501 catalyst which had previously been ion ex ⁇ changed to the acid form. The temperature was main ⁇ tained at 25°C. for six hours. Analysis of the re ⁇ action mixture showed 51% conversion of the propionic acid to t-butyl propionate.
- Example 2 The reactor used in Example 2 was charged with 120.0 grams of methacrylic acid, 100.0 grams of tetra ⁇ hydrofuran, 5.0 grams of Nafion 501 exchanged to the acid form, and 125.0 grams of isobutylene, the reaction was stirred and maintained at 25°C. for 24 hours. Samples were taken and analyzed as follows:
