| 20140371485 | Synthetic Acid and Associated Methods - Glycine is an organic compound that can be used in the making of a synthetic acid that obviates all the drawbacks of strong acids such as hydrochloric acid. The new compound is made by dissolving glycine in water, in a weight ratio of approximately 1:1 to 1:1.5. The solution is mixed until the glycine is essentially fully dissolved in the water. Once dissolution is complete, hydrogen chloride gas is dissolved in the solution to produce the new compound, which can be referred to as hydrogen glycine. A method of taming an acid includes adding the solution of hydrogen glycine to the acid in an effective amount for substantially preventing corrosion and fuming during an application of a mixture thereof. | 12-18-2014 |
| 20150126776 | PROCESS FOR PREPARING N-ACYL AMINO ACID SALTS - Improved processes for making an N-acyl amino acid salt from a fatty alkyl ester or a polyol ester are disclosed. Each process uses a polyol selected from glycerin or propylene glycol in an amount effective to keep the reaction mixture fluid until conversion to the N-acyl amino acid salt reaches the desired level of completion. In one process, a fatty alkyl ester reacts with an amino acid salt in the presence of glycerin or propylene glycol to produce an N-acyl amino acid salt. In another process, a polyol ester reacts with the amino acid salt in the presence of added glycerin or propylene glycol to produce the N-acyl amino acid salt. We surprisingly found that an effective amount of glycerin or propylene glycol minimizes or eliminates reaction mixture solidification or foaming, reduces color, and minimizes the level of di- and tripeptide by-products. In a related process, water is added when conversion of the amino acid salt to the N-acyl amino acid salt is in the range of 50 to 90 mole %. Water addition improves processability, advances conversion without producing excessive soap, and helps to ensure that the N-acyl amino acid salt will have low color and a small proportion of by-products. | 05-07-2015 |
