It is mainly used as a building block in the production of polymers such as polytrimethylene terephthalate. [2] 1,3-Propanediol can be formulated into a variety of industrial products including composites, adhesives, laminates, coatings, moldings, aliphatic polyesters, and copolyesters. It is also a common solvent.
Bronopol is used in consumer products as an effective preservative agent, as well as a wide variety of industrial applications (almost any industrial water system is a potential environment for bacterial growth, leading to slime and corrosion problems - in many of these systems bronopol can be a highly effective treatment).
Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid.It is almost odorless and has a faintly sweet taste. Its chemical formula is CH 3 CH(OH)CH 2 OH. . As it contains two alcohol groups, it is classified as a d
3-methyl-4-(2,6,6-trimethylcyclohex-2-enyl)but-3-en-2-one fragrance ingredient [6] aluminium chlorohydrate: basic aluminium chloride Al 2 (OH) 5 Cl or Al 2 (OH) x Cl 6−x (0<x<6) antitranspirant aluminium hydroxide: Al(OH) 3: opacifying agent; skin protectant aqua water: solvent ascorbyl glucoside: C 12 H 18 O 11: carrier of vitamin C (water ...
2,2-Disubstituted propane-1,3-diols are prepared in this way. Examples include 2-methyl-2-propyl-1,3-propanediol and neopentyl glycol. 1,3-Diols can be prepared by hydration of α,β-unsaturated ketones and aldehydes. The resulting keto-alcohol is hydrogenated. Another route involves the hydroformylation of epoxides followed by hydrogenation of ...
Bioseparation of 1,3-propanediol is a biochemical process for production of 1,3-propanediol (PDO). PDO is an organic compound with many commercial applications. Conventionally, PDO is produced from crude oil products such as propylene or ethylene oxide .
Another example is the bioconversion of glycerol to 1,3-propanediol, which is part of scientific research for many decades. Another example of bioconversion is the conversion of organic materials , such as plant or animal waste, into usable products or energy sources by biological processes or agents, such as certain microorganisms , some ...
Its relatively high viscosity and low volatility are advantageous in coatings, cleansers, cosmetics, solvents, lubricants, and hydraulic fluids. [9] Although it is an irritant at higher concentrations, it is sometimes used in skin care, hair care, soap, and eye cosmetic products at concentrations ranging from 0.1% - 25%. [10] [11]
