Production of low color refined isophorone |
| abstract |
LOW COLOR ISOPHORONE Abstract of the Disclosure Crude isophorone is refined by contacting it with aqueous caustic followed by washing and fractional distillation. This procedure provides an efficient method of treating crude isophorone to produce low-colored, refined product without a neutralization step or corrosion of the processing equipment. The pre-ferred caustic employed in this procedure is sodium hy-droxide. |
