OTC acetyl chloride

(1/3) > >>

Natrix:
SCl2 and SOCl3 are generated in situ:

S + Cl2 -> SCl2
CH3-COOH + SCl2 + Cl2 -> CH3-COCl + SOCl3 + HCl
CH3-COOH + SOCl3 -> CH3-COCl + SO2 + HCl

V.Auger, A.Behal, Bl. (3) 2, 145 (1889)

and Houben-Weyl VIII, p.475

does this also work with chloroacetic acid?

ApprenticeCook:
do you mean to produce chloro-acetylchloride? by this method? should work via same route and method..... couldnt see why not.... (objections?)

But nice route for acetyl chloride, nice for acetic anhydride req's.

Yes it does, see Patent DE146796, Patent DE157816 and JACS 61 2142-50 (1939) & 62 925-29 (1940) ;)

yei:
I notice that there is an HCl generated for every Cl2 consumed. Could this mean that a mixture of S and TCCA would also work?

phenethyl_man:
perhaps a foolish question but..  where abouts can elemental sulfur be found over-the-counter?
