(Case Studies in Sustainable Collection Care Session) Solvents, Scents and Sensibility: Sequestering and Minimizing

Sign up or log in to save this to your schedule and see who's attending!

A simple review of solubility theory will be presented to put the discussion of solvent substitution into context. The three component forces that are active and make solvents liquid rather than gases will be reviewed as will the concept of aromaticity.

The thermodynamic underpinnings of solubility theory (Hildebrand solubility theory) will be very briefly introduced as a preface to discussion of Hansen solubility parameters.

The three dimensional Hansen space will be discussed where solvents are represented as points in the space and solutes are represented as spheres. Mixtures of two solvents are represented by a line between the two points and mixtures between three and more points will be discussed and demonstrated.

The Teas diagram, solvents and mixtures of solvents will be discussed. The advantages and limitations of the Teas diagram will be presented and demonstrated.

Solvents will be briefly introduced with a summary of their relative health and environmental dangers. Absent mechanical controls to protect the conservator (but not necessarily the
environment) from exposure, we all strive to use the safest solvents/solvent systems in the safest way and yet still function. Applying Hansen solubility theory to the task of finding solvent mixtures that can be used to substitute for the least bio-friendly solvents will be presented and discussed.
