Years ago, coffee is decaffeinated by steaming the coffee beans for 30 minutes and then followed by treating them with methylene chloride solvents to leach out caffeine.

The Paint and Allied Products Manufacturing Area Source rulemaking would apply to paint, ink, and adhesive manufacturing facilities that use cadmium, chromium, lead, nickel, benzene, or methylene chloride, and are categorized as "area sources" [emit less than 10 tons-per-year of a single Hazardous Air Pollutant (HAP) or less than 25 tons-per-year of a mixture of HAPs].

: Conventional coffees are typically decaffeinated using carcinogenic solvents, such as methylene chloride or ethyl acetate.

The terminals have been tested for exposure to popular cleaning chemicals such as alcohol or methylene chloride.

This process involves soaking the beans in water and then "washing" them in methylene chloride to absorb the caffeine from the bean.

During its production of pharmaceutical-grade chemicals, Pfizer used substances such as methanol, hydrogen chloride, methylene chloride, MTBE, hexane, toluene and others that the EPA classifies as hazardous air pollutants.

Methylene chloride were dried and purified according to standard laboratory methods.

The oxathiinone precursors (30-50 mg) were dissolved in ~2 mL of methylene chloride and the solutions were evaporated inside the test tube under an argon purge to achieve better coverage of its inner surface by the solids, which assisted sublimation.
