Hydrogenolysis Process. Patty alcohols are produced by hydrogenolysis of methyl esters or fatty acids ia the presence of a heterogeneous catalyst at 20,700—31,000 kPa (3000—4500 psi) and 250—300°C ia conversions of 90—98%. A higher conversion can be achieved using more rigorous reaction conditions, but it is accompanied by a significant amount of hydrocarbon production. 

Patty esters (wax esters), formed by ester interchange of the product alcohol and the starting material in the hydrogenolysis reactors, are later separated from the product by distillation. Unreacted methyl esters are also converted to fatty esters in the distillation step... 

In April of 1991, the U.S. National Aeronautics and Space Administration concluded that o2one depletion was occurring even faster than had been estimated, and at the third meeting of the patties to the Montreal Protocol in June of 1991, an eadiet phaseout of controlled substances was proposed. An assessment of the technical and economic consequences of a 1997 phaseout is cuttendy underway, and further acceleration of the phaseout schedule to as soon as 1995 seems likely. Many countnes already have undatetaHy banned or curbed the use of controlled substances well ahead of the Montreal Protocol timetable. As of eadyjuly 1992, there were 81 parties to the Protocol. 

The lambda type is nongelling, and functions as a thickner. Iota-carrageenan has been recommended (45) for use in formulating low fat ground beef due to its abihty to retain moisture, especially through a freeze—thaw cycle which is typical for ground beef patties. Oat bran and oat fiber can also be used to improve moisture retention and mouth feel. Modified starches can be used as binders to maintain juiciness and tenderness in low fat meat products. Maltodextrins (dextrose equivalent less than 20) may be used as binders up to 3.5% in finished meat products. Other carbohydrates such as konjac flour, alginate, microcrystalline cellulose, methylceUulose, and carboxymethylceUulose have also been used in low fat meat products (see CELLULOSE ETHERs). 

Once the patent appHcation is complete and the inventor has made a formal declaration of inventorship, the appHcation is filed with the U.S. PTO. In the U.S. PTO, the appHcation is the subject of a thorough, formal, and substantive examination by a patent examiner. Once the patent examiner is convinced that the patent appHcation satisfies the statutory requirements provided for under the laws of the United States, the patent appHcation will be allowed to issue as a patent. Issuance takes the form of a pubHcation provided by the U.S. Government. The pubHcation of patents occurs only on Tuesdays that ate not federal hoHdays. At the time of issuance, the patent is assigned a number and made pubHc in a form which allows all interested patties to obtain access to it. 

Patty amines and chemical products derived from the amines are used in many industries. Uses for the nitrogen derivatives may be broken down as follows as a percentage of total market fabric softeners (46%), oil field chemicals (15%), asphalt emulsifiers (10%), petroleum additives (10%), mining (4%), and others (15%) (8).
