Easy way to make phosphorus pentachloride with easy to get reagents
Phosphorus pentachloride is hard to obtain but there's a feasible synthesis of it using calcium phosphide and calcium phosphide can be made by the
thermocabron reduction of calcium phosphate with carbon the only problem is that it generates co and reacts with water to form phosphine gas but
calcium phosphide is heated to 230c with chlorine the calcium phosphide reacts with the chlorine to form calcium 2 chloride and phosphorus
trichloroide which will be further oxidized to pentachloride with fairly high yields there is more detail on small scale sysnthis of labatory reagents
I'm sorry for my grammar

Have you tried this method?

Not sure why calcium phosphide would be preferred over a safer transition metal phosphide which does not hydrolyse to phosphine and ferrophosphorous
is commercially available.

Almost all metal phosphides hydrolysis to phosphine

Thats not true. Most metal phosphides don't react with water at all. Only phosphides of highly electropositive elements (alkali metals, alkaline earth
metals, aluminium) react with water to produce phosphine (and traces of diphosphane and other polyphosphanes).

My bad I'm not very knowledgeable about transition metal chem

I agree with Bedlasky. I have ferrophosphorus and I have Cu3P (copper(I) phosphide). Both are quite inert solids and do not react with water. Even
acids, like HCl or dilute H2SO4, do not decompose these phosphides.
On the other hand, zinc phosphide (also a transition metal phosphide) does react with water, albeit slowly. With acids, Zn3P2 gives phosphine more
quickly, but not violently.

The only bad thing about this process is the potential generation of phosphine I might have to do some experimenting with transition metal phosphides
thank you for the idea.

Zinc is a transition metal in name only, though. Chemically, it acts like an s-block metal.

I personally don't consider it as transition metal, because it have full d orbital. That's why it behave mostly like p-block metal. Same for Cd and
Hg.
