chloral hydrate | ||||||
i was wondering about making chloral hydrate in the following manor: first prep and isolate ethanal by distillation off a ethnol/H20/HOCl soltn. ethanal boils at just a little over room temp. then add the ethanal to a soltn of H20/NaOH about 3mols of NaOH/mol of ethanal. then add to this a solutin of chlorine water with abit more then 3mols of Cl2 for every mol of ethanal. some chloroform/formic acid would proboly be made as a byprouct, but these should be seperable by distllation. finally the trichlroethanal would have to be hydrated, i don't know how this would best done. |

i did see that, but it wasn't really what i wanted, it was brand specific as opposed to chemical specific, and it really didn't give much indication of the chemistry going on. |

my thoughts exactly | ||||||
I was trying to convert the brand specific proportions to an exact mole ingredient and fell short without further knowledge of the products involved, and little enthusiasm to reasearch. |
