The Occupational Safety and Health Administration (OSHA) has set the legal limit (Permissible exposure limit) for Stoddard solvent exposure in the workplace as 500 ppm (2900 mg/m3) over an 8-hour workday. N.H. Choulis, J.K. Aronson, in Side Effects of Drugs Annual, 2005. Mineral spirits are an inexpensive petroleum-based replacement for the vegetable-based turpentine. There were no clinical symptoms of organophosphate ingestion, despite reduced erythrocyte and plasma cholinesterase activity. 0000014364 00000 n S.R. Hydrocarbons are quite abundant in modern society; their use includes fuels, paints, paint and stain removers, dry cleaning solutions, lamp oil, lubricants, rubber cement, and solvents. The type refers to whether the solvent has been subjected to hydrodesulfurization (removal of sulfur) alone (type 1), solvent extraction (type 2) or hydrogenation (type 3). They are also used to thin inks used in making monoprints. It can be found in various cleaning agents where its low evaporation point comes in handy and as a dilution agent for paints, varnish and asphalt. In western Europe about 60% of the total white spirit consumption is used in paints, lacquers and varnishes. Pneumoencephalography on a man who regularly inhaled paint thinner (“certified pure” toluene) provided the first structural evidence that solvent abuse could cause brain atrophy (Knox & Nelson, 1966). [8][failed verification] Artists use mineral spirits as an alternative to turpentine since it is less flammable and less toxic. In Corinth, she infamously murdered the reigning monarch and his daughter with an incendiary compound, called naphtha, typically reserved for ancient naval combat. In Australia and New Zealand "white spirit" can also refer to. Stoddard solvent is a refined petroleum distillate derived from the naphtha and kerosene carbon ranges (C7–C12) in crude oil.

Which of the following is not considered a hazardous waste? These products are also known by many common names, including mineral spirit, mineral turpentine, Medea, princess of Colchis—a late Bronze Age (c. 1200–1000 BC) kingdom of the Black Sea—was personally associated with the cult rites of Diana, Hera, and Hecate; known for her physical beauty and potentially nefarious pharmaceutical knowledge, she was reportedly involved with the monarchies of several Greek city-states, including Athens and Corinth, and the foundation of several temples. Fels-Naptha® is a particularly famous brand of soap that contains this chemical as a solvent. Use care when Hydrocarbons are a heterogeneous group of organic substances that are primarily composed of carbon and hydrogen molecules and can be derived from either petroleum or wood. [citation needed] It cannot be used as an alternative to white gas, which is a much more volatile gasoline-like fuel. In the atmosphere, merphos will exist as an aerosol and be removed by gravitational settling and readily oxidized to DEF. Mineral spirits are often used inside liquid-filled compasses and gauges. woodfinishing • It is used for fuel and cleaning. Based on global expansion in economy and population, this area of toxicology warrants continuous monitoring as the demand for increased air traffic continues. Some of the forms of jet fuels (JP-8 and JP-4) were found to be negative in mutagenicity tests but JP-4 showed an increase in unscheduled DNA synthesis. bob • Mineral turpentine is chemically very different from turpentine, which mainly consists of pinene, and it has inferior solvent properties. [2][3] These effects in painters were first studied in 1970s in the Nordic countries. Toluene is now generally produced along with benzene, xylenes, and C9 aromatics by the catalytic reforming of C6–C9 naphthas. 0000012996 00000 n The downside of naphtha, compared with mineral spirits, is that it has a stronger odor. Naphtha is used primarily as feedstock for producing a high octane gasoline component via the catalytic reforming process. 0000001638 00000 n I bought a squeezy bottle of Ronsonol lighter fluid a year or two ago, mainly to clean off sticky label residue from labels, because I had heard it was naptha. The fact that merphos is expected to adsorb strongly to particulate matter in the water column, apparently did not impede its oxidation. We offer affordable, on-site naphtha solvent recovery for facilities of all sizes. Humans use naphtha in three main ways: for industrial purposes, as a solvent and as a fuel. 0000023973 00000 n You only pay for the solvents that are recovered from your waste; we also offer lease and single-use options for batch processing requirements. Solvent Recycling Systems, LLC © 2017 | All Rights Reserved | Terms & Conditions, In the face of growing regulations and EPA reporting rules, many facilities have to look at removing any additional operating costs when it comes to naphtha solvent recycling. Coal tar, shale and petroleum make up three distinct forms of naphtha, each formed under different conditions and used for different purposes for their chemical properties. Medea, a “master-sorceress,” had a longstanding reputation throughout the Mediterranean for possessing particular skill with the use of so-called drug-induced “fires,” including the group of drugs that caused “oistros,” the ecstatic state induced in ios-rite initiates who reportedly suffer from sensations of extreme “burning.”49 Like the Echidnae in Greece, Asia Minor, Italy, and North Africa—the priestesses who perpetuated her oracular rites—Medea prepared drugs in her vagina, and administered her own vaginal excreta as the communal “burning purple” of ios-rite mystery initiation.50, The “burning purple,” a mixture of Medea’s vaginal excreta combined with ritual drugs, was also used as an ink. Toluene has been detected in emissions from volcanoes, forest fires, and crude oil. However, n-hexane is present also in the human body as by-products of lipid peroxidation, independently of environmental pollution. While it's used mainly as a paint thinner or a cleaning agent, its other uses include paint and varnish diluents, asphalt diluents, rubber industry solvents, dry-cleaning, cigarette lighters, and portable camping stove and lantern fuels. It is difficult to extrapolate results from experiments done in a laboratory setting using purified substances to the sort of complex real-world exposures in which people encounter various materials over time. Naphtha Uses.
