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.
