Applicant's summary and conclusion
- Conclusions:
- Vapor pressures were calculated according to the method of Mackay (1982). The method which is applicable for hydrocarbons that boil above 100°C is considered valid for the terphenyls. It was validated with 72 different compounds with known vapor pressures. The mean error was 1.25.
The estimated vapor pressures of o-, m- and p- terphenyls are in line with the vapor pressure of other polyphenyls. The vapour pressure decreases with each additional ring, leading to a vapour pressure for the terphenyls that is between the vapour pressure of the bi- and quaterphenyls. - Executive summary:
Vapor pressures of some polyphenyls were estimated from known physical properties i.e. melting point and boiling point. Vapor pressure ranged from 1.6x10-5to 3.0x10-14atmosphere. The vapor pressure decreased dramatically as the number of rings increased – approximately 2 to 3 orders of magnitude for each additional ring. The estimated vapor pressure of the o-, m- and p-terphenyls ranged from 4.3 x 10-7to 8.0 x 10-10atmosphere.
