Diethylsuccinoylsuccinate is an organic compound with the formula [CH 2 C(OH)=C(CO 2 Et)] 2 (Et = ethyl). A tetrasubstituted derivative of 1,4-cyclohexadiene, the compound is the enol tautomer of the corresponding cyclohexadione. [1] It is produced by base-induced condensation of diethyl succinate: [2] 2 EtO 2 CCH 2 CH 2 CO 2 Et [CH 2 C(OH)=C ...
The following compounds are liquid at room temperature and are completely miscible with water; ... (CH 2) 4 O: tetrahydrofuran: 109-99-9 C 6 H 14 O 4: triethylene ...
Diethyl succinate is the diethyl ester of succinate. It is a colorless liquid with the formula (CH 2 CO 2 Et) 2 (Et = ethyl). The organic molecule contains two ester groups. This ester is a versatile chemical intermediate. A colorless liquid, diethyl succinate is formed by Fischer esterification of succinic acid and ethanol.
Assumption 2. The self-ionization of water can be ignored. This assumption is not, strictly speaking, valid with pH values close to 7, half the value of pK w, the constant for self-ionization of water. In this case the mass-balance equation for hydrogen should be extended to take account of the self-ionization of water.
These uses exploit its basicity. Diethyl ether is a popular non-polar solvent in liquid-liquid extraction. As an extractant, it is immiscible with and less dense than water. Although immiscible, it has significant solubility in water (6.05 g/(100 ml) at 25 °C [2]) and dissolves 1.5 g/(100 g) (1.0 g/(100 ml)) water at 25 °C. [13]
The structure of a typical NONOate group. In chemistry, a NONOate is a compound having the chemical formula R 1 R 2 N−(NO −)−N=O, where R 1 and R 2 are alkyl groups. One example for this is 1,1-diethyl-2-hydroxy-2-nitrosohydrazine, or diethylamine dinitric oxide.
Denatonium, usually available as denatonium benzoate (under trade names such as Denatrol, BITTERANT-b, BITTER+PLUS, Bitrex, Bitrix, and Aversion) and as denatonium saccharinate (BITTERANT-s), is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharinate.

Sodium diethyldithiocarbamate typically crystallizes from water as the trihydrate NaS 2 CN(C 2 H 5) 2. 3H 2 O. The anhydrous salt and the trihydrate are often used interchangeably. [1] Sodium diethyldithiocarbamate is obtained by treating carbon disulfide with diethylamine in the presence of sodium hydroxide: CS 2 + HN(C 2 H 5) 2 + NaOH → NaS ...
