Chemical Solvents

Select a solvent based on compatibility with the materials involved (plastics, metals, coatings), solvency power for the target substance, evaporation rate, toxicity and PPE requirements, and regulatory restrictions; consult safety data sheets (SDS) and perform small-scale compatibility tests when possible

Store solvents in labeled, approved containers in a cool, ventilated area away from ignition sources; use appropriate PPE (gloves, goggles, respirators), keep SDS accessible, and follow local regulations for secondary containment, grounding/bonding during transfer, and spill response

Purity affects reactivity, residue, and yield; specifications are given as percent purity, parts per million of water or impurities, or grades (industrial, technical, reagent); choose higher-purity grades for sensitive processes like lab work or electronics cleaning

Industrial solvents in this category commonly span from low-cost bulk industrial grades under $50 per unit to higher-purity or specialty solvents that can cost several hundred dollars; balance initial cost against required purity, yield impacts, disposal costs, and any regulatory compliance expenses

Segregate used solvents by type and contamination level, consult local hazardous-waste regulations, use licensed waste haulers or approved recycling/distillation services, and never pour solvents down drains or into the environment

Check hazard classification, composition/ingredients, exposure limits (TLV/PEL), recommended PPE, first-aid measures, flammability and reactivity data, storage and disposal instructions, and emergency contact information

Not reliably—solvent selection depends on polarity, solvency strength, boiling point, and compatibility with substrates; a solvent that works for cleaning may not be suitable for thinning or extraction without testing and review of safety and regulatory implications
