    PROPYLENE GLYCOL

    ~ also known as 1,2-propanediol; 1,2-dihydroxypropane, Propane-1,2-diol; 57-55-6; 1,2-Propylene glycol; etc. is a is a synthetic organic compound. The global propylene glycol market is projected to reach USD 4.60 billion by 2021, at a CAGR of 5.8% from 2016 to 2021
    Chemical structure: C3H8O2 (CH3CHOHCH2OH).  It is sometimes called α-propylene glycol to distinguish it from the isomer propane-1,3-diol (β-propylene glycol).
    Properties: Propylene glycol is a clear, colorless and hygroscopic liquid. Propylene glycol contains an asymmetrical carbon atom, so it has two enantiomers. The commercial product is a racemic mixture. Pure optical isomers can be obtained by hydration of optically pure propylene oxide.
    It is non-corrosive and has very low volatility and toxicity...

    ADIPIC ACID

    ~ also known as Hexanedioic acid; 1,4-Butanedicarboxylic acid; 124-04-9; Adipinic acid; Adilactetten; etc. is the most important dicarboxylic acid. About 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for nylon production.
    Chemical structure: C6H10O4 or HOOC(CH2)4COOH. Adipic acid is a dicarboxylic acid.
    Properties: Adipic acid is a white crystalline solid. It is insoluble in water.
    Production: 
    1. Adipic acid is produced from a mixture of cyclohexanol and cyclohexanone called “KA oil”, i.e. ketone-alcohol oil. The KA oil is oxidized with nitric acid to give adipic acid, via a multistep pathway. Early in the reaction, the cyclohexanol is converted to the ketone, releasing nitrous acid. Among its many reactions, the cyclohex...

    cured epoxy molecule

    ~ also known as polyepoxides; EP 828 acrylate; ED 20 acrylate; E 44, acrylate; YD 128 acrylate; Pacrosir VE 196, etc. is a class of reactive prepolymers and polymers which contain epoxide groups.

    Epoxy resins may be reacted either with themselves through catalytic homopolymerization, or with a wide range of co-reactants including polyfunctional amines, acids, phenols, alcohols, and thiols. These co-reactants are often called hardeners or curatives, and the cross-linking reaction is referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer. As of 2006, the epoxy industry amounts to more than US$5 billion in North America and about US$15 billion worldwide.

    Chemical structure: C21H25ClO5...
