Process chemicals

Solution properties, computed and cited.

Density, dynamic viscosity and specific heat capacity of aqueous process chemicals as a function of concentration and temperature. Every value is generated from a published property correlation — not entered by hand — and each page is cross-checked against an independently cited reference before it is published.

Method

Property values are computed offline from published correlations — the Laliberté (2009) aqueous-electrolyte model for the acids and bases, and CoolProp's incompressible-fluid correlations for the glycols — and committed as auditable data; the site renders only those committed values and never computes chemistry at request time. Each substance carries its generating model, validity range, source list and a cited validation point on its page.
