| 20110301361 | METHOD OF RETAINING THE QUALITY OF 2-METHYL-3-(3,4-METHYLENEDIOXYPHENYL) PROPANAL AND PROCESS FOR PRODUCING THE SAME - The present invention relates to [1] a method for keeping a quality of 2-methyl-3-(3,4-methylenedioxyphenyl)propanal useful as a perfume, which comprises incorporating from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene in the 2-methyl-3-(3,4-methylenedioxyphenyl)propanal; [2] a process for producing 2-methyl-3-(3,4-methylenedioxyphenyl)propanal having a content range from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene; and [3] 2-methyl-3-(3,4-methylenedioxyphenyl)propanal having a content range from 50 to 3000 ppm of 1-acetyl-3,4-methylenedioxybenzene. | 12-08-2011 |
| 20120035376 | METHODS FOR THE MANUFACTURE OF ACETALS AND KETALS, AND THE ACETALS AND KETALS PRODUCED THEREBY - 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. | 02-09-2012 |
| 20120323021 | METHOD FOR PRODUCING A HIGH-PURITY AROMATIC METHYL ALCOHOL AND HIGH-PURITY AROMATIC METHYL ALCOHOL COMPOSITION HAVING EXCELLENT PRESERVATION STABILITY - 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. | 12-20-2012 |
| 20150080585 | METHODS FOR THE MANUFACTURE OF ACETALS AND KETALS, AND THE ACETALS AND KETALS PRODUCED THEREBY - 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. | 03-19-2015 |
| 20160083310 | METHOD FOR STABILIZING A COMPOSITION CONTAINING AT LEAST ONE PRODUCT OF INTERNAL DEHYDRATION OF A HYDROGENATED SUGAR, RESULTING COMPOSITION AND USES THEREOF - A method for improving the stability of compositions of a product for internal dehydration of a hydrogenated sugar, in particular an isosorbide composition, the method involving the use of monoethanolamine, diethanolamine, triethanolamine and the mixtures thereof as a stabilization agent. The resulting compositions and their various uses thereof are also described. | 03-24-2016 |
