Green Solvents is a simple reference-card app that provides information about the environmental properties of common solvents.
Green Solvents is an app that provides a reference list of solvents, with auxiliary information about their health, safety and environmental malignancy, and features for looking them up online. The source data is derived from the solvent selection guide provided by the ACS Green Chemical Institute Pharmaceutical Roundtable and the GlaxoSmithKline Solvent Selection Guide. Background information about the app's genesis can be found here.
The main view shows a scrollable list of solvents, which are organised into several categories: acids, alcohols, aromatics, bases, dipolar aprotics, esters, ethers, halogenated solvents, hydrocarbons and ketones. Each solvent is shown with an icon that indicates its type, and these can be filtered by pressing the buttons along the top panel. Solvents are also shown with icons that summarise the toxicity in general, which are colour coded for severity.
Tapping on any of the solvents bring up a detail view. For example, benzene presents a very serious health risk and is flammable, but it is at least not particularly reactive, and otherwise average:
Sulfolane, on the other hand, presents a nasty waste disposal problem:
Seven properties are rated on a scale of 1 to 10, where 1 is for most benign and 10 is for most toxic/hazardous. These properties are derived from the underlying solvent guides, some of which have been merged when two guides provide conflicting values.
More information about the chemical is available underneath, including some essential physical properties, and links to external databases such as NCBI PubChem, RSC ChemSpider and the EPA CompTox Dashboard.
Green Solvents is a very simple app which makes relevant information conveniently available. Links to additional resources are available when more detail is required.
