An integrated process for the production of one or more acetylene derivatives is provided. The integrated process includes a) partially oxidizing a hydrocarbon feedstock to produce a partial oxidation mixture comprising H.sub.2, CO, and acetylene, b) providing the H.sub.2 and CO of the partial oxidation mixture to a collocated methanol production process to produce a methanol-containing effluent; c) providing the methanol-containing effluent to a collocated carbonylation process to produce an acetic acid-containing effluent; and d) providing the acetylene of the partial oxidation mixture and the acetic acid-containing effluent to one or more of the collocated acetylene-derivative processes following: i) a vinyl acetate monomer production process; ii) an oxidation unit for the production of formaldehyde from the methanol-containing effluent; iii) a vinyl chloride monomer production process, and/or iv) a 1,4-butanediol production process.

Dicarboxylic acids, such as adipic acid, and diesters, such as adipates, may be produced by hydrogenating alkynes that may be produced from raw materials salvaged from waste stream processes. The carbons of the dicarboxylic acids are provided by alkynes generated from biomass waste and carbon dioxide recovered from waste streams such as exhaust gases.
