PROCESS FOR PREPARATION OF TERT-BUTYLAMINE AND PROPIONIC ACID SALTS FROM N-TERTIARY BUTYL ACRYLAMIDE
-
Page/Page column 15; 16;, (2021/11/13)
Disclosed is a process (100) for conversion of N-tertiary butyl acrylamide to tert-butylamine and salts of propionic acid. The process comprises of first selectively reducing the vinylic double bond in N-tertiary butyl acrylamide by catalytic hydrogenation of an alcoholic solution of N-tertiary butyl acrylamide to provide N-tertiary buyl propanamide; recovering the hydrogenation catalyst by filtering the solution and treating the solution with an alkali to produce N-tertiary butylamine and corresponding alkali salt of propionic acid. The process converts of N-tertiary butyl acrylamide into value added products at milder reaction conditions, without producing any hazardous byproducts and effluents.
METHOD FOR PRODUCING CALCIUM DIPROPIONATE
-
Paragraph 0010, (2018/07/26)
The invention relates to a solid-material method for producing calcium dipropionate in a pressure-resistant solid-state mixing reactor by charging calcium oxide, calcium hydroxide or calcium carbonate or mixtures of these calcium compounds, and adding propionic acid by a reaction directly in the solid phase under a pressure that is increased above normal pressure.
Process for producing a calcium carboxylate
-
Page/Page column 7-8, (2010/02/10)
A process for producing a calcium carboxylate comprising contacting a nitrile compound, a calcium compound selected from calcium hydroxide, calcium oxide or mixtures thereof, and water at a temperature of about 90°C to about 250°C at a sufficient pressure and for a sufficient time to produce a reaction mixture comprising calcium carboxylate.

Page 5; 6, (2008/06/13)
A process for producing a calcium carboxylate comprising contacting a nitrile compound, a calcium compound selected from calcium hydroxide, calcium oxide or mixtures thereof, and water at a temperature of about 90° C. to about 250° C. at a sufficient pressure and for a sufficient time to produce a reaction mixture comprising calcium carboxylate.
A METHOD OF MAKING SALT
-
Page/Page column 14, (2008/06/13)
A method of making the salt of an acid, includes the steps of combining and mixing the acid and a base selected from the oxides, hydroxides and carbonates of sodium, potassium, calcium and magnesium, in a first reaction zone over a first period to produce a reaction mixture. The reaction mixture is transferred at the end of the first period from the first reaction zone to a second reaction zone the transferring step being carried out over a second period. Heat generated by reaction between the acid and the base in the second reaction zone drives off sufficient water to produce a product mixture containing less than about 8 % (m/m) water. The first period is between about 1 and 180 seconds and the second period is between about 2 and 60 seconds.
Solid phase synthesis of salts of organic acid
-
, (2008/06/13)
A process for the solid-phase synthesis of salts of organic acids in a granular, free-flowing, and dust-free form particularly suited for use as animal feed additives. A liquid organic acid is applied to an inert, absorbent carrier. A solid base is then added during stirring. The acid is slowly released from the carrier preventing the fast reactions that lead to the formation of clumps. The exothermic reaction releases heat which assists in reducing the moisture content of the product.
Methods of preparation and using antimicrobial products
-
, (2008/06/13)
Novel antimicrobial products and methods of making and using the same are shown, whereby the products can be used in the same or greater percentages as conventional microbial growth inhibitors without imparting an off-flavor, taste, color or odor to the products in which they are used. The antimicrobial products are formed by reacting azodicarbonamide or an ammonia gas with a compound selected from the group consisting of benzoic acid, sodium benzoate, calcium benzoate, potassium benzoate, acetic acid, sodium diacetate, paraben, niacin, calcium acetate, calcium diacetate, citric acid, lactic acid, fumaric acid, sorbic acid, sodium sorbate, calcium sorbate, potassium sorbate, propionic acid, sodium propionate, calcium propionate, potassium propionate and mixtures thereof. In one embodiment, the product is prepared by placing a layer of azodicarbonamide on a substrate and covering the layer with a gas permeable separator. The antimicrobial compound is then added on top of the separator, and the combination is heated to form the final product. In another embodiment, the product is prepared by exposing the antimicrobial compound to an ammonia gas. The ammonia gas reacts with free acids in the antimicrobial compound to convert the free acids into ammonium salts, thereby eliminating off-flavor and off-odor of the resulting antimicrobial product. The antimicrobial products prepared according to the present invention are suitable for use in foodstuffs, sanitation products, cosmetics, pharmaceuticals, and so forth.

The antimicrobial compound is then added on top of the separator, and the combination is heated to cause the azodicarbonamide to decompose and release ammonia gas to form the final product. In another embodiment, the product is prepared by exposing the antimicrobial compound to an ammonia gas.
