If you have a high pressure reactor a good solvent would be acetone for rearanging the hydrochloride salt at 180 °C for 30 minutes. Hippler |

mineral oil | ||||||
mineral oil boils very high, is made of simple alkanes, and is cheap and OTC. (shouldn't you be using the freebase?) It's good to bee back! Don't trust your computer!! |

Vaaguh said "using hydrochloride salt", which seems less likely to dissolve in oil than the freebase... It's good to bee back! Don't trust your computer!! |

probably | ||||||
acetone is a good, versitile solvent for nonpolars and some polars. However, it boils too low. Why again did you want to use it? What was wrong with using the best available substitute for decane or whatever, which is mineral oil? I don't think any acetone is required. It will just boil off anyway. It's good to bee back! Don't trust your computer!! |

another preference | ||||||
A great advantage of using a high boiling solvent that also bears a ketone group is that during the rearangement of the ketimine in the hydrochloride form the byproducts that are formed will stay into the solution, this makes it easy for the rearanged ketamine hydrochloride to be filtered off.
