Propanoic Acid Uses

Propanoic Acid is a vital wonderful chemical and an intermediate for countless different other fantastic chemicals. Mostly utilized as food and feed active ingredients, and second of all used in family medicines, precious natural herbs, medicines, flavors, and so forth. In regards to grain and feed active ingredients, the application effect of propionic acid is fantastic, and the intake is proliferating.
( 1) Artificial additive. Calcium propionate and salt propionate can stay clear of food perishing brought on by microbial activity, extend food storage room time, and are properly utilized for the preservation of bread and breads.
( 2) Grain chemical. Propanoic Acid has actually been efficiently used to stay clear of mold and caking of grains, giving a brand-new strategy for lasting storage room and conservation of grains.
( 3) Beverage preservative. Tests have in fact revealed that Propanoic Acid, salt propionate and calcium propionate are all good feed preservation agents and are generally taken advantage of to preserve feed for pigs, livestock, sheep and chicken, among which calcium propionate has one of the most effective impact. Zinc propionate and cadmium propionate in propionates are motorists for polyester production of terephthalate; there are lots of kind of propionate esters with their actual own usages, and can be utilized as solvents, spices, pharmaceutical intermediates, and cosmetics Additives, material modifiers, cigarette filter plasticizers, gas oil antiknock reps, anti-bacterial agents, and so forth. The intermediates of propionic acid byproducts, 2-chloropropionic acid, lactic acid, 2,2-dichloropropionic acid, 2-bromopropionic acid, 3-chloropropionic acid, propionitrile, and propionyl chloride, are utilized in lots of drugs, chemicals and herbicides respectively. Manufacturing of agents, food boosters, flavors and different other things.

Propanoic Acid Production Method

Propanoic Acid is discovered in fermented or ruined dairy products, molasses and starch. In the early days, propionic acid mostly originated from byproducts of specific items, such as nitration of paraffin hydrocarbons, fermentation of sugar or starch, completely dry distillation of timber, oxidation of light hydrocarbons to acetic acid, and so on, every one of which generated small amounts of propionic acid. Currently, the major approaches for industrial production of propionic acid consist of oxidation of propionaldehyde, carboxylation of ethanol, and healing of light hydrocarbons as byproducts when creating acetic acid.
1. Propionaldehyde is quickly oxidized into propanoic acid under the activity of air or other oxidants. The oxidation process can use salts such as cobalt, manganese and copper as drivers, or it can be carried out without a stimulant under typical stress or somewhat enhanced stress. The yield of this technique can reach more than 95%, and greater than 90% of the propionic acid manufacturing in the United States is created by this method.
2. Oxidation of light hydrocarbons is one of the major approaches for creating acetic acid. For every single 100t of acetic acid produced, 25t of formic acid and 10t of propionic acid can be created as by-products.
3. The method of ethanol carboxylation is to utilize ethanol, carbon monoxide and water as resources, and execute catalytic carboxylation under high temperature and high pressure to obtain propionic acid. DuPont in the USA uses this approach to build a manufacturing system with a yearly output of 5,000 bunches. This approach has severe process conditions and high tools product needs, which limits its development.
4. Direct oxidation of low-carbon hydrocarbons. When oxidizing low-carbon hydrocarbons as raw materials to create acetic acid, formic acid and propionic acid can be co-produced, and propionic acid can be obtained after separation.
5. Reppe approach: Ethylene reacts with carbon monoxide gas and water under the catalysis of nickel carbonyl to synthesize propionic acid in one step. Response conditions are 250-320 ° C and 10-30MPa.
6. Propylonitrile hydrolysis technique is produced by hydrolysis of propionitrile under the catalysis of focused sulfuric acid.
7. Polymer acid method is produced by hydrogenation and decrease of acrylic acid.
