Colleagues,
I am working on an educational piece that involves a reaction using P2S5. This compound reacts with water to give H2S. I have never used this compound and I cannot find an SOP online that describes useful
procedures. My immediate question this: How does one weigh a quantity of this compound? Is it so reactive in air that it degrades quickly (in addition to producing flammable H2S), or is the water (“humidity”) reaction slow enough that brief exposure
to air is safe? Thus: weigh using a balance on the benchtop, or weigh inside a glove box? A reply from someone who has used this compound would be appreciated.
Thanks,
Dave
