Useful:

• Chemical Classes: Toxic Gases & Vapors -> Acids, Inorganic
• Canonical SMILES: OS(=O)(=O)O
• Recent EU Clinical Trials: A two-part, open-label, clinical study to assess the safety, tolerability and activity of intravenous doses of ICT01 in combination with low-dose subcutaneous interleukin-2 in patients with advanced solid tumors (EVICTION-2)
• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is very corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. Inhalation may cause asthma-like reactions (RADS). Medical observation is indicated.
• Effects of Long Term Exposure: Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation may cause effects on the lungs. Risk of tooth erosion upon repeated or prolongated exposure to an aerosol of this substance. Mists of this strong inorganic acid are carcinogenic to humans.

Technology Process of Sulfuric(VI) acid

There total 1045 articles about Sulfuric(VI) acid which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
