| titleOfInvention | Production of 4-hydroxy-2,5-dimethyl-3(2h)-furanone |
| abstract | PURPOSE: To obtain the subject compound useful as a perfumery for tableware in high efficiency on an industrial scale at a low cost without causing side effect by reacting dibromodihydroxyhexanone with a tertiary amine, thereby cyclizing the starting compound. n CONSTITUTION: The objective compound can be produced by cyclizing 3,3- dibromo-2,5-dihydroxyhexan-4-one with preferably 2-5 times mol of a tertiary amine (e.g. triethylamine, triethanolamine or dimethylaniline). n COPYRIGHT: (C)1991,JPO&Japio |
