Introduction

It has a camphor-like smell. The dew becomes a dimer, which is oxidized in the air to produce 4,4, 6-trimethyl-1, cyclohexanedione. Soluble in alcohol, ether and acetone, miscible with most organic solvents, solubility in water: 12g/L (20°C). There is the possibility of cancer. There’s tear-jerking irritation.
