| titleOfInvention | Racemic hydroxyaryl-glycolic acids, preparation process and new products from said acids |
| abstract | PRECISION OF DISCLOSURE: The invention relates to a preparation process. of racemic hydroxyarylglycolic acids and products new resulting from this process we condense in water in the presence of an alkaline agent, at a temperature between 35 and 100 ° C, glyoxylic acid on an excess or not a phenolic aromatic derivative, other than phenol, having at least one proton on one of the vertices ortho or para with respect to the phenol function. This process allows obtaining new acids such as acid hydroxy-4 tert-butyl-3 mandelic, hydroxy-2 acid 5-tert-butyl mandelic, 3-chloro-4-hydroxy-mandelic acid lique, 2-fluoro-4 hydroxy-mandelic acid, acid dimethoxy 3,5 hydroxy-4 mandelic monohydrate, acid hydroxy-2 methyl-5 mandelic acid (hydroxy-1 naphthyl-2) glycolic, 4-ethyl-2-hydroxy-mandelic acid, and 4-hydroxy-3-methyl-mandelic acid. |
