Preparation of 4-Methyl-2-pentanone:
4-Methyl-2-pentanone is manufactured from acetone via a three-step process. Firstly acetone undergoes an aldol condensation to give diacetone alcohol, which readily dehydrates to give mesityl oxide. Mesityl oxide can then be hydrogenated to give MIBK:
Uses of 4-Methyl-2-pentanone:
it can be used to produce 4-methyl-pentan-2-ol at temperature of 82 °C. It will need reagent KOH and solvent propan-2-ol with reaction time of 12 hours. The yield is about 96%.
When you are using 4-Methyl-2-pentanone , please be cautious about it as the following:
It is highly flammable and toxic by inhalation, in contact with skin and if swallowed. please keep away from sources of ignition - No smoking. Besides, this chemical is irritating to eyes and respiratory system harmful by inhalation. It repeated exposure may cause skin dryness or cracking. When you are using it, wear suitable suitable protective clothing and gloves and do not empty into drains. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible).
