| titleOfInvention | Production of butane-1,4-diol |
| abstract | Butane-1 ,4-diol is produced by converting allyl alcohol to an allyl t-alkyl or -cycloalkyl ether of the general formula: n<CHEM>n wherein R1 and R2 each, independently of the other, represent a C1 to C4 alkyl radical, and R3 and R4 each, inde. pendently of the other, represent a hydrogen atom or a C, to C3 alkyl radical, or wherein R1 represents a C1 to C4 alkyl radical, R2 and R3 together with the carbon atoms to which they are attached form a 5-membered or 6-membered cycloaliphatic ring, and R4 represents a hydrogen atom or a C1 to C3 alkyl radical, followed by reacting resulting compound of formula (III) under hydroformylation conditions with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst to form a corresponding aldehyd-ether of the general formula. n<CHEM>n reducing resulting aldehyd-ether of the general formula (II) to form a corresponding hydroxy-ether of the general formula: n<CHEM>n and cleaving resulting hydroxy-ether of the general formu-la (II) to give butane-1 ,4-diol. Typically R1 and R2 each represent a methyl group whilst R3 and R4 each represent a hydrogen atom. The alkene of the general formula: |
