Latent heat - polyphosphoric acid

Latent heat - polyphosphoric acid

Latent heat - polyphosphoric acid

(OP)
Hi,

I need to know the latent heat of vapourisation for polyphosphoric acid at ~atmospheric pressure (56mbarg) for a fire relief calculation.

Unfortunately, the MSDS's I have seen just says: 'not pertinent' as they do with phosphoric acid.

Is there any reason for this? Does it break down to some thing else? Can anyone tell me the latent heat please.

Many thanks,

Alf

I GOGGLED "phosphoric acid latent heat" and got several hits.
