Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
The idealized combustion of mustard gas in oxygen produces hydrochloric acid and sulfuric acid, in addition to carbon dioxide and water: (ClC 2 H 4) 2 S + 7 O 2 → 4 CO 2 + 2 H 2 O + 2 HCl + H 2 SO 4. Bis(2-chloroethyl)sulfide reacts with sodium hydroxide, giving divinyl sulfide: (ClC 2 H 4) 2 S + 2 NaOH → (CH 2 =CH) 2 S + 2 H 2 O + 2 NaCl ...
The mustard plant is any one of several plant species in the genera Brassica, Rhamphospermum and Sinapis in the family Brassicaceae (the mustard family). Mustard seed is used as a spice . Grinding and mixing the seeds with water, vinegar, or other liquids creates the yellow condiment known as prepared mustard .
The Capparaceae have long been considered closely related to and have often been included in the Brassicaceae, the mustard family (APG, 1998), in part because both groups produce glucosinolate (mustard oil) compounds. Subsequent molecular studies [3] support Capparaceae sensu stricto as paraphyletic with respect to the Brassicaceae.
The mustard plant is known as "chicken mustard", "multishoot mustard", and "nine-head mustard". big-stem mustard Stem Mustard (茎用芥/芥菜头) Previously identified as B. juncea subsp. tsatsai var. tumida. [3] The mustard plant with knobby, fist-sized, swollen green stem is known as "big-stem mustard" or "swollen-stem mustard".
Brassicaceae (/ ˌ b r æ s ɪ ˈ k eɪ s iː ˌ iː,-s i ˌ aɪ /) or (the older) Cruciferae (/ k r uː ˈ s ɪ f ər i /) [2] is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family.
Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification ...
