For example, treatment of benzenediazonium chloride with benzene (an aromatic compound) in the presence of sodium hydroxide gives diphenyl: [C 6 H 5 N 2] + Cl − + C 6 H 6 → (C 6 H 5) 2 + N 2 + HCl. This reaction is known as the Gomberg–Bachmann reaction. A similar conversion is also achieved by treating benzenediazonium chloride with ...
The tetrafluoroborate can be obtained from crude benzenediazonium chloride by salt metathesis using tetrafluoroboric acid. [C 6 H 5 N 2]Cl + HBF 4 → [C 6 H 5 N 2]BF 4 + HCl. The tetrafluoroborate is more stable than the chloride. [2]
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo-p-dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [3] with the chemical formula C 12 H 4 Cl 4 O 2. Pure TCDD is a colorless solid with no distinguishable odor at room temperature.
Other dioxin congeners including PCDFs and PCBs with dioxin-like toxicity, are given a toxicity rating from 0 to 1, where TCDD = 1 (see Dioxins and dioxin-like compounds). This toxicity rating is called the Toxic Equivalence Factor concept, or TEF. TEFs are consensus values and, because of the strong species dependence for toxicity, are listed ...
4-Nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is a pale yellow solid. It is a precursor to 4-nitrobenzoyl chloride, the precursor to the anesthetic procaine and folic acid. It is also a precursor to 4-aminobenzoic acid. [6]
2,4-Dinitrochlorobenzene (DNCB) is an organic compound with the chemical formula (O 2 N) 2 C 6 H 3 Cl. It is a yellow solid that is soluble in organic solvents . It is an intermediate for the industrial production of other compounds.
Urinary alkalinization with sodium bicarbonate may be useful for barbiturate poisoning, targeting a urinary pH greater than 7.5 and ensuring urine output surpasses 2 mL/kg/min. [10] If a person is drowsy but awake and can swallow and breathe without difficulty, the treatment can be as simple as monitoring the person closely.
A review published in 1911 examined 27 cases of cicutoxin poisoning, 21 of which had resulted in death [7] – though some of these cases involved deliberate poisoning. [8] This review included a case where a family of five used Cicuta extracts as a topical treatment for itching , resulting in the deaths of two children, a report that suggests ...
