Trial Number 0

Trial Purpose:

To generate a list of products that could be used to replace Methylene Chloride.

Date Run:

07/07/2005

Experiment Procedure:

Using the laboratory's database for solvent cleaning substitution, the lab generated a list of products that could be used in place of Methylene Chloride. A comparison of physical properties was conducted as well.

Trial Results:

A list of 19 products was compiled. Various physical characteristics were compared to Methylene Chloride. The physical properties researched include: Vapor Pressure, Latent Heat, Surface tension, Boiling Point, Flash Point, ODP, GWP, VOC, SNAP , KB value, Exposure Level, Chemical Formula, Molecular Wt, Freezing Pt, Sp Gr, Density, Vapor Density, Specific Heat, Refractive Index, Viscosity, Solubility of water, Solubility in water, Solvent-water Azetrope BP, Flammable limits and the Hansen Parameters.
Not all properties were identified for the listed products.
