You need no extra chlorine to make phosgene from tetrachloroethylene. In fact there are almost enough atoms in tetrachloroethylene to make 2 phosgenes. I suspect
the welding arc turns oxygen to ozone which then makes two phosgenes directly from tetrachloroethylene.
Phosgene wasn't used very often in WWI and WWII. Phosgene only was itself in lab conditions. Hitler actually planned to use it but was exposed to it and found it so painful he opted for other gases like mustard gas. It was used by the Japanese. It was made by making chloroform and then allowing the chloroform to decompose through exposure to light, which would yield Phosgene gas. They probably did it in a more industrial-efficient way but decomposing chloroform is the easiest way to do it.
A correction. The brake cleaner compound that can produce phosgene is Tetrachloroethylene, a chlorinated hydrocarbon. It is non flammable and cannot be used to create "fireballs" Other non chlorinated brake cleaners are made with just plain hydrocarbons and are flammable, some are very flammable and smell like either and naphtha, but will not create phosgene. Phosgene is created mainly by the exposure of the clorinated cleaner by the intense UV radiation from welding, especially tig
@ismasamov55 Naturally I submit to your assertion that phosgene gas can not be created without the element chlorine. This is an undisputed fact. However, if you purchase a can of non-chlorinated brake cleaner the warning on the label indicates that it can produce hydrogen chloride gas and phosgene gas. How can this be if there is no chlorine in the brake cleaner?
My guess:Non chlorinated brake cleaner still has chlorine in it. Probably just a reduced amount.

@ismasamov55 IF what your saying is brake cleaner isn't flammable your full of shit. It's used it in potato launchers quite effectively. It only takes a small amount with a spark to get a maximum explosion to launch.
One of the byproducts of burning Difluoroethane (computer duster) is HF.When HF (or Hydrogen Fluoride) gas mixes with the moisture in your eyes, lungs, sinuses, forehead, etc, it forms hydrofluoric acid. HCl (or Hydrogen Chloride) is similar to HF. When HCl mixes with water, it forms hydrochloric acid.
But at least HF and HCl are very pungent and give some warning.
It was better known as 'mustard gas' in the First WW. BTW I used to own a Alfa Romeo 1900 Superleggera Sprint (1952) which had plexiglass rear quarter-light windows to further lighten it. Wished I had kept it and restored it like you. Good job! BTW I sold it to the chairman of the Alfa club in the UK...over 30 years ago!
meh, literally almost everything "has been found to cause cancer by state of california".

Hes correct, there are multiple types of brake clean. The brand being shown in the video is in fact non-flammable.

Phosgene was different than mustard gas, more deadly in much lower concentrations, not that it matters too much. They are both horrific.
The Alfa I restored also had the plexi rear windows. Cheers mate!
