Process and system for preparing electronic-grade isopropanol by hydrogenating acetone

A process for preparing isopropanol by hydrogenating acetone raw material, comprising:

• (1) introducing the acetone raw material into an acetone pre-oxidation processor to pre-oxidize the reducing impurities to obtain a pre-oxidized acetone raw material;
• and
• (2) introducing an acetone feed into an acetone hydrogenation reactor for hydrogenation reaction to obtain a crude isopropanol product;
• wherein the acetone feed is the pre-oxidized acetone raw material obtained from step (1), or a refined acetone feedstock obtained by an optional intermediate treatment (1-2) of the pre-oxidized acetone raw material.
