Definitions
- the present invention relates to a process for the preparation of n-octadienols by dimerization and hydration of butadiene in the presence of a catalyst and water.
- a reaction mixture containing 1,3-butadiene, water, a solvent is formed in which the butadiene and the water are at least partially soluble in the presence of a catalyst comprising compounds of transition metals (palladium or platinum) and a phosphine and a co-catalyst consisting of carbon dioxide.
- a catalyst comprising compounds of transition metals (palladium or platinum) and a phosphine and a co-catalyst consisting of carbon dioxide.
- the phosphine is chosen from known compounds, insoluble in water, such as trialkylphosphines, triarylphosphines, tertiary alkylarylphosphines.
- the solvent is chosen from dialkyl ethers, cyclic ethers, lower alkyl ethers of polyalcohols or polyoxyalkylene glycols, alkyloxy- and aryloxy-polyalkenoxy-alkanols, ketones, amides, pyridine derivatives, tallow oxides, sulfones such as sulfolane, esters, aromatic solvents, aliphatic hydrocarbons, olefins.
- Compounds known to react with the metal can be added to the reaction mixture. These Compounds can serve as additional protection to prevent the deposition of metal during the reaction and during subsequent processing to prepare the catalyst for recycling. These compounds are listed in a list of more than 50 nitrogen products including, among others, trimethylamine, triethylamine, tri-n-octylamine, dimethyldodecylamine.
- This solubility is provided by the presence of at least one sulfonate group, M being a cationic residue of mineral or organic origin.
- This patent discloses a process for hydrodimerization of butadiene in the presence of water and a catalyst consisting of at least one of these soluble phosphines and of a transition metal in metallic form or in the form of a compound of said metal chosen from Pd, Ni, Pt, Co or Rh, said catalyst passing into solution in said water.

- This process can also be implemented in the presence of aliphatic or aromatic tertiary amines.
- Examples 7 to 16 relating the synthesis of octadienols, without the presence of tertiary amine or of solvent, indicate at best for example 10 a conversion rate of 76% and a selectivity of 64% in octa-2.7 - dienol-1-ol and 20% for octa-1,7 dien-3-ol from butadiene consumed, i.e. an ol-l / (ol-l + ol-3) selectivity equal to only 76% (100x64 / 84).
