| titleOfInvention | Production of polyalkyl-2- 2,4-dihydroxyphenyl -7-hydroxy- chroman |
| abstract | NEW MATERIAL:Compounds of formula I (R 1 , R 2 , R 4 are 1W3C alkyl; R 3 is H, 1W3C alkyl). n EXAMPLE: 2,4,4-Trimethyl-2-(2,4-dihydroxyphenyl)-7-hydroxychroman. n USE: Synthetic intermediate of agricultural chemicals, medicines, additives for resins or copolymerizable monomer for modifying reins. n PREPARATION: The condensation reaction of 1mol of resorcine with 0.4W3mol of an unsaturated aliphatic ketone of formula II is conducted in the presence of an acidic catalyst such as Broensted acid or cation exchange resin at 40W130°C to produce the compound of formula I. n COPYRIGHT: (C)1982,JPO&Japio |
