臨床応用
1,1,1-Trichloro-2-methyl-2-propanol is a white crystallinesolid with a camphorlike aroma. It occurs in an anhydrousform and a hemihydrate form, both of which sublime at roomtemperature and pressure. Chlorobutanol is slightly soluble inwater and soluble in alcohol and in organic solvents.
Chlorobutanol is used as a bacteriostatic agent in pharmaceuticalsfor injection, ophthalmic use, and intranasal administration.It is unstable when heated in aqueous solution, especially at pH greater than 7. Under these conditions,chlorobutanol undergoes elimination. Solutions with a pHof approximately 5 are reasonably stable at 25°C.Chlorobutanol is stable in oils and organic solvents.
廃棄物の処理
A suitable method of destruction of chlorobu tanol is the burning of its solution in a com bustible solvent in a chemical incinerator.
