[2] The pure form of nitrite was first made by the Swedish chemist Carl Wilhelm Scheele working in the laboratory of his pharmacy in the market town of Köping. While working with Butter at the Edinburgh Royal Infirmary in the 1860s, Brunton noted that the pain of angina could be lessened by venesection and wrongly concluded that the pain must be due to elevated blood pressure. OSHA Vacated PELs: Sodium nitrite: No OSHA Vacated PELs are listed for this chemical. He heated potassium nitrate at red heat for half an hour and obtained what he recognized as a new “salt.” The two compounds (potassium nitrate and nitrite) were characterized by Péligot and the reaction was established as 2KNO3 → 2KNO2 + O2. The most significant observation was that even a small dose of <0.5 grains (≈30 mg) given by mouth caused, at first, an increase in arterial blood pressure, followed by a moderate decrease. [3], Potassium nitrite forms potassium nitrate when heated in the presence of oxygen from 550 °C to 790 °C. A mixture with potassium cyanide may cause an explosion. 1946-47].
