MIBK is an excellent solvent with medium boiling point, it can be used as the solvent for paint, nitrocellulose, ethyl cellulose, tape, wax and several resins. Also, it is widely used as the dewaxing agent, extraction agent, the RM for antiaging agent synthesis and etc.
| Production Process | Advantages and Disadvantages | Status |
| Iso-Propanol Process | It is the earliest process for MIBK production. Its disadvantages included. | It has been phased out. |
| The availability of the iso-propanol feedstock is limited. | ||
| The production cost is relatively higher. | ||
| The by-product amount is large. | ||
| Acetone Three-Step Process | This process has the following advantages. | This process has been successfully industrialized for many years, and up to now it is still one of the main MIBK production processes. |
| The intermediate/product from every step (methyglyoxal, mesityl oxide, MIBK) can be as the finished product for sales, thereby the production is quiet flexible. | ||
| The catalyst used in every step has good activity and selectivity. | ||
| The reaction conditions are relatively mild; the operation is easy. | ||
| However, its disadvantages lies in long process flow, high investment and high production cost. | ||
| Acetone One-Step Process | The advantages of this process includes short process flow, less investment, higer conversion yield and low energy consumption. | It is the most competitive and the most prospective process. |
