HYDROFORMYLATION PROCESS FOR PRODUCING 1,6-DISUBSTITUTED HEXANE DERIVATIVES

The invention relates to a process for the production of 1,6-difunctionalized hexane derivatives from 1,3-diunsaturated hydrocarbons, preferably butadiene, wherein a hydroformylation with carbon monoxide and hydrogen is performed in the presence of an at least dihydric alkanol and during the hydroformylation the temperature is increased. The reaction yields the acetals of the 1,6-hexanedial derivatives which are isolated and further reacted to obtain the desired 1,6-difunctionalized hexane derivatives, in particular 1,6-hexanediamine, 1,6-hexanediol and adipic acid.

The present invention provides a process for the production of green hydrogen gas as a source of clean energy from methanol in addition to quantitative yields of formic acid, catalyzed by a range of group (VIII) complexes based on variety of ligands. Group (VIII) complexes consists of a series of new pincer ruthenium and related Group (VIII) complexes. All of the catalytic complexes are employed towards catalytic methanol reforming for generation of green hydrogen at relatively ambient conditions (<100 C. and 1 atm). Methanol has been used as an efficient and practical hydrogen storage material. A mechanistic pathway for the reaction has been proposed based on the evidence of NMR studies and formation of intermediate, generates hydrogen gas. Both hydrogen and formic acid have immense market value.
