Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
Halogenation of the alcohol in muriatic acid afforded 4-Chlorobenzhydryl chloride [134-83-8] (3). Alkylation with one equivalent of piperazine gives 1-(4-Chlorobenzhydryl)piperazine [303-26-4] ( 4 ). Alkylation of the remaining nitrogen with Cinnamyl Bromide [4392-24-9] ( 5 ) completed the synthesis of Clocinizine ( 6 ).
Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value.Acute chlorine gas poisoning primarily affects the respiratory system, causing difficulty breathing, cough, irritation of the eyes, nose, and throat, and sometimes skin irritation.
Aristolochic acid (contained in herbs in the genus Aristolochia e.g. Aristolochia serpentaria (Virginia snakeroot), Aristolochia reticulata (Texas snakeroot) and in Chinese herbs such as Aristolochia fangchi and Aristolochia manshuriensis [7] (banned in China and withdrawn from Chinese Pharmacopoea 2005; Stephania tetrandra and Magnolia ...
In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine). An alternative name is chlorhydrate, which comes from French. An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid.
An Olympic equestrian athlete had his results from the Paris Olympics thrown out after he inadvertently tested positive for a banned substance after giving his sick dog eye drops.
Sulfamic acid is a moderately strong acid, K a = 0.101 (pK a = 0.995). Because the solid is not hygroscopic, it is used as a standard in acidimetry (quantitative assays of acid content). H 3 NSO 3 + NaOH → NaH 2 NSO 3 + H 2 O. Double deprotonation can be effected in liquid ammonia to give the anion HNSO 2− 3. [6] H 3 NSO 3 + 2 NH 3 → HNSO ...
Chloroethane is produced by hydrochlorination of ethylene: [11]. C 2 H 4 + HCl → C 2 H 5 Cl. At various times in the past, chloroethane has also been produced from ethanol and hydrochloric acid, from ethane and chlorine, or from ethanol and phosphorus trichloride, but these routes are no longer economical.
