| titleOfInvention | PROCESS FOR THE PRODUCTION OF HIGHER MOLECULAR ALPHA, BETA-UNSATABLED ALDEHYDE |
| abstract | The prepn. of high-molecular aldehydes (I) by the reaction of II with III: R9-CR8=CR7-CR5R6-CR3R4-CR2=CR1-CHO (I) R9-CR5=CR7-CR5R6-OR10 (II) C(H)R3R4-CR2=CR1-CHO (III) is carried out at increased temp. and between normal press. and 250 atmos. excess, in liquid phase. In the formulae, R1 and R2 are H, 1-4C alkyl or (alkyl-substd.) phenyl, R3, R5 and R7 are H or 1-4C alkyl, R4 is H or an (un)satd., (un)branched 1-12C (cyclo)aliphatic gp., R8 is 1-4C alkyl or, if R9 is phenyl, is H, R9 is an (un)branched, (un)satd. 1-12C (cyclo)aliphatic gp. in which C-C bonds may be interrupted by O or -O-CO-, or may be (alkyl-substd.) phenyl, and R10 is H or the acyl residue from a 1-5C carboxylic acid. I are raw materials for natural prods. and perfumes, e.g. beta-ionone, farnesol and phytol. |
