Yesterday I was working with oxalyl chloride in lab without fume hood and aluminium trichloride was nearby but accidentally my partner spilled that aluminium trichloride in oxalyl chloride.

            now we are scared whether  this aluminium trichloride have decomposed this oxalyl chloride to phosgene?

*we havent smelt any strange  odour.

*Our room was 100 cubic meter.

*We were there upto 2 minutes from spillage and left immediately to avoid inhalation.

 My main question is how spontaneoud reaction is between oxalyl chloride and aluminium chloride to form phosgene

I haven't seen any evidence that oxalyl chloride and aluminium chloride produces phosgene, but it is a known prep to form aromatic acid chlorides. What sort of scale were you working on? Why were you not using a fume cupboard?

effects are delayed upto 24 hr in phosgene and lethal conc in ppm is till debate in human data from 10ppm to 5oppm ie upto max 20gram in your 100 meter room which seems impossible by just adding few amount to oxalyl chloride.


Do any guy know spontaneous reliable chemical reaction to produce phosgene in laboratory scale?
