Oxygenated hydrocarbon production system with acidic impurity removal resin column

A method of producing an oxygenated hydrocarbon, the method comprising:

• monoesterifying maleic anhydride with a monoesterification alcohol having 1 to 3 carbon atoms to form a monoester stream comprising a maleic acid monoester;
• diesterifying the maleic acid monoester with a diesterification alcohol having 1 to 3 carbon atoms to form a crude diester stream comprising a maleic acid diester;
• passing the crude diester stream through an anion exchange resin to form a deacidified diester stream and an acidified resin;
• and
• hydrogenating the deacidified diester stream using hydrogen gas and a hydrogenation catalyst to form an oxygenated hydrocarbon, wherein:
• the oxygenated hydrocarbon is at least one selected from the group consisting of tetrahydrofuran, 1,4-butanediol, and gamma butyrolactone;
• and
• the deacidified diester stream comprises less than 0.5 mol % maleic acid monoester based on a total number of moles of maleic anhyride derivatives present in deacidified diester stream.
