Compound In Which The Hetero Ring Is Five-membered With Preservative Or Stabilizer Patents (Class 549/205)
  • Publication number: 20150080585
    Abstract: A method for producing a product that comprises glycerol ketal of ethyl levulinate or propylene glycol ketal of ethyl levulinate comprises reacting either glycerol or propylene glycol with ethyl levulinate in the presence of a homogenous or heterogeneous catalyst system in a reactor system. The ethyl levulinate and either glycerol or propylene glycol are heated to remove water, polyol, and excess ethyl levulinate. The excess ethyl levulinate and polyol is recycled back to the reactor. The product is distilled in a specific fashion and optionally treated by means of a stabilizing agent or acid species removal bed, to obtain a composition comprising glycerol ketal of ethyl levulinate or propylene glycol ketal of ethyl levulinate wherein the composition comprises less than or equal to about 2 wt % contaminants.

  • Publication number: 20120323021
    Abstract: An object of the present invention is to provide a high-purity aromatic methyl alcohol compound having reduced a bis(arylmethyl)ether compound as a side product mixed thereinto and a high-purity aromatic methyl alcohol composition having excellent preservation stability and methods for producing them. The object of the present invention is achieved by a method for producing a high-purity aromatic methyl alcohol compound, which comprises obtaining a high-purity aromatic methyl alcohol compound in high yield from an aromatic methyl alcohol-containing crude product by subjecting the crude product to distillation in the presence of an anti-decomposition agent. Further, the object for the preservation stability is achieved by producing a high-purity aromatic methyl alcohol composition using the obtained high-purity aromatic methyl alcohol compound.
