- C07C 29/03 by addition of hydroxy groups to unsaturated carbon-to-carbon bonds, e.g. with the aid of H2O2 (by simultaneous introduction of -OH groups and halogens C07C29/64)
- C07C 29/09 by hydrolysis
- C07C 29/128 by alcoholysis
- C07C 29/132 by reduction of an oxygen containing functional group
- C07C 29/15 by reduction of oxides of carbon exclusively
- C07C 29/16 by oxo-reaction combined with reduction
- C07C 29/17 by hydrogenation of carbon-to-carbon double or triple bonds
- C07C 29/32 increasing the number of carbon atoms by reactions without formation of -OH groups
- C07C 29/36 increasing the number of carbon atoms by reactions with formation of hydroxy groups, which may occur via intermediates being derivatives of hydroxy, e.g. O-metal
- C07C 29/44 increasing the number of carbon atoms by addition reactions, i.e. reactions involving at least one carbon-to-carbon double or triple bond (C07C29/16 takes precedence)
- C07C 29/48 by oxidation reactions with formation of hydroxy groups
- C07C 29/56 by isomerisation
- C07C 29/58 by elimination of halogen, e.g. by hydrogenolysis, splitting-off (C07C29/124 takes precedence)
- C07C 29/60 by elimination of -OH groups, e.g. by dehydration (C07C29/34 takes precedence)
- C07C 29/62 by introduction of halogen; by substitution of halogen atoms by other halogen atoms
- C07C 29/64 by simultaneous introduction of -OH groups and halogens
- C07C 29/68 Preparation of metal alcoholates (C07C29/42, C07C29/54 take precedence)
- C07C 29/74 Separation; Purification; Use of additives, e.g. for stabilisation
