2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
2,4-Dichlorophenol (2,4-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH. It is a white solid that is mildly acidic (pK a = 7.9). It is produced on a large scale as a precursor to the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).
2,4,5-Trichlorophenoxyacetic acid (also known as 2,4,5-T), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants. It was developed in the late 1940s, synthesized by reaction of 2,4,5-Trichlorophenol and chloroacetic acid. It was widely used in the agricultural industry until being phased out, starting ...
Techno-economic assessment or techno-economic analysis (abbreviated TEA) is a method of analyzing the economic performance of an industrial process, product, or service. The methodology originates from earlier work on combining technical, economic and risk assessments for chemical production processes. [ 1 ]
In some cases economic predictions of a model merely assert the direction of movement of economic variables, and so the functional relationships are used only in a qualitative sense: for example, if the price of an item increases, then the demand for that item will decrease. For such models, economists often use two-dimensional graphs instead ...
Economics (/ ˌ ɛ k ə ˈ n ɒ m ɪ k s, ˌ iː k ə-/) [1] [2] is a social science that studies the production, distribution, and consumption of goods and services. [3] [4] Economics focuses on the behaviour and interactions of economic agents and how economies work.
The history of economic thought is the study of the philosophies of the different thinkers and theories in the subjects that later became political economy and economics, from the ancient world to the present day. This field encompasses many disparate schools of economic thought.
2,4-Dithiapentane is the dimethyldithioacetal of formaldehyde. Its synthesis was first reported in 1941. Its synthesis was first reported in 1941. [ 1 ] [ 2 ] It is industrially prepared by the acid-catalyzed condensation of methyl mercaptan , the main aromatic compound in both halitosis and foot odor and a secondary compound in flatulence ...
