Production:


The invention provides a method for producing isophthalic acid, characterized by including subjecting a m-phenylene compound to liquid-phase oxidation reaction by use of a molecular-oxygen-containing gas in the presence of a catalyst at least containing a heavy metal compound and a bromine compound, and hydrous acetic acid having a water content of 1 to 15 mass %, to thereby yield a slurry; regulating the temperature of the slurry to 35 to 140° C., to thereby cause isophthalic acid to precipitate; removing the isophthalic acid through to solid-liquid separation to thereby recover a mother liqu-or; and recovering the catalyst from the mother liq-uor through a series of reusing at least a portion of the catalyst in the liquid-phase oxidation reaction.

An adsorption step including regulating the ratio “amount by mole of bromide ions in the mother liq-uor/total amount by mole of heavy metal ions in the mother liq-uor” to 0.3 to 3, and then exposing the mother liq-uor to a pyridine-ring-containing chelate resin which has been heated to 35 to 140° C.

Propylene Glycol is an odorless and colorless liquid; boiling point 188 C, freezing point -39 C. Propylene glycol is prepared by hydrolysis of propylene oxide. Large amount of propylene glycol is used in the plastics industry for the manufacture of polyester fibers and alkyd resins.


Features:


  • It is used as a main ingredient in automobile antifreeze and engine-cooling liquids and in brake and hydraulic fluids due to its useful properties of low freezing point, involatility and low corrosive activity.
  • It is used in the preparation of body-care surfactants. Propylene glycol is replacing ethylene glycol and ethanol as it is less toxic than ethylene glycol.
  • Propylene glycol is described as a "generally recognized as safe for use in food, cosmetics, and medicines" by FDA. Propylene glycol USP grade is used as a non-toxic antifreeze in breweries and dairies.
  • It is used as a humectant in foods and cosmetics.
  • It is used as a solvent for colouring or flavouring agents as well as in many oral, injectable or topical pharmaceuticals.
  • Its antibacterial property is applied in the preparation of sanitizing lotions.

    Heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16. When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is a 100% iso-octane). Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctane which is expressed as the percentage of isooctane in heptane and is listed on pumps for gasoline (petrol) dispensed globally.
