Vapor pressure of ammonium benzoate?

Does anyone have a reference for the vapor pressure of ammonium benzoate?

Checked all my references and web search came up empty.

Thanks

Update:

The VP will be small, but it does have one. For more info see something like DiCHAN.

    This material is an organic salt. It will have no measurable vapor pressure until is heated well above its melt point and/or have high vacuum applied. Even then, it may still decompose rather than vaporize.

    If there is a vapor pressure, it probably ammonia due to the reversible reaction:

    NH4O2CC6H5 (s) ↔ NH3 (g) + C6H5CO2H (s)
