  • Patent number: 9938170
    Abstract: 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. Also disclosed is a method for adjusting the pH of a fluid, the method comprising adding an effective amount of a solution to the fluid for adjusting the pH thereof to a desired level wherein the solution is prepared by mixing glycine in water to form a glycine solution; and adding hydrogen chloride to the glycine solution.

  • Patent number: 9302980
    Abstract: The problem to be solved by the present invention is to easily and efficiently produce an amino acid having 2 to 7 carbon atoms as a high-purity solid without complicated operation, which is useful as a synthetic intermediate for medicines or agrochemicals. The present invention is characterized in comprising a step of precipitating solid amino acid with high purity. In the present invention, the by-produced salt composed of the sulfonic acid and the amine was removed to the mother liquor by reacting an amine with a sulfonic acid salt of amino acid in an aprotic polar solvent, or by reacting a sulfonic acid with an amine salt of amino acid in an aprotic polar solvent. The sulfonic acid salt of amino acid, for example, may be produced by reacting a N-(tert-butoxycarbonyl) amino acid with a sulfonic acid, or by reacting an amino acid tert-butyl ester with a sulfonic acid.

  • Publication number: 20150126776
    Abstract: 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 %.

  • Publication number: 20140039219
    Abstract: The present invention provides a method for making 6-aminocaproic acid as an active pharmaceutical ingredient. The method comprises: performing a hydrolysis procedure to have ?-caprolactam react with acid or base to generate a first reaction mixture, performing a modification procedure to have a solubility regulating agent reacts with 6-aminocaproic acid in the first reaction mixture to form a second reaction mixture including an aminocaproic acid intermediate, performing a separation procedure to have the intermediate separated from the second reaction mixture and performing a hydrogenation procedure to have the aminocaproic acid intermediate hydrogenated to form a 6-aminocaproic acid product.

  • Patent number: 8642792
    Abstract: The invention relates to a method for the synthesis of amino acids/esters of general formula NH2—(CH2)n—COOR in which n is an integer between 5 and 14, and R is either H or an alkyl radical including from 1 to 4 carbon atoms, from natural long-chain mono-unsaturated fatty acids or esters including at least 10 adjacent carbon atoms per molecule, said method comprising: first converting, if necessary, said natural long-chain fatty acid or ester into a monounsaturated fatty acid/ester of general formula R1—(CH2)m—CH?CH—(CH2)p—COOR in which R1 is H, CH3 or a COOR radical, m is an integer between 0 and 14 and p is an integer between 2 and 11, then submitting the latter to a crossed catalytic metathesis reaction with a compound of formula R2—CH?CH—R3 in which R2 is either H or CN and R3 is CN or CH2NH2, provided that if R2 is CN, R3 can be only CN, and finally converting the resulting product of the general formula R3—CH?CH—(CH2)p—COOR into an amino-acid, either by hydrogenation, or by hydrogenation of the triple t

  • Publication number: 20130303723
    Abstract: The invention provides a non-naturally occurring microbial organism having a 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid pathway. The microbial organism contains at least one exogenous nucleic acid encoding an enzyme in the respective 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid pathway. The invention additionally provides a method for producing 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid. The method can include culturing a 6-aminocaproic acid, caprolactam or hexametheylenediamine producing microbial organism, where the microbial organism expresses at least one exogenous nucleic acid encoding a 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid pathway enzyme in a sufficient amount to produce the respective product, under conditions and for a sufficient period of time to produce 6-aminocaproic acid, caprolactam, hexametheylenediamine or levulinic acid.

  • Patent number: 8552180
    Abstract: The present invention provides a method for separating an amide from an amino acid ionic liquid. The method includes the step of providing a polar solvent and an extracting agent to the amino acid ionic liquid, so as to separate the amide from the amino acid ionic liquid. In the method of the present invention, there is no need to add ammonium for neutralization, such that no byproduct, ammonium sulfate, is formed. In addition, after the amide is separated from the amino acid ionic liquid, the amino acid ionic liquid can be recycled.
