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 ...
2,4,5-Trichlorophenol (TCP) is an organochloride with the molecular formula C 6 H 3 Cl 3 O.It has been used as a fungicide and herbicide. Precursor chemical used in the production of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) and hexachlorophene involves the intermediate production of 2,4,5-trichlorophenol (TCP) and the formation of 2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly referred to ...
The ethyl hexyl form of the compound is rapidly hydrolyzed in soil and water to form the 2,4-D acid. [18] 2,4-D has a low binding affinity in mineral soils and sediment, and in those conditions is considered intermediately to highly mobile, and therefore likely to leach if not degraded. [18] In aerobic aquatic environments, the half life is 15 ...
The "10" is the ball diameter in millimeters. The "3000" is the force in kilograms force. The hardness may also be shown as XXX HB YYD 2. The XXX is the force to apply (in kgf) on a material of type YY (5 for aluminum alloys, 10 for copper alloys, 30 for steels). Thus a typical steel hardness could be written: 250 HB 30D 2. It could be a ...

As you wait for prescription drug costs to come down from the clouds, here's how you can save money on the medications you need. 1. Use a coupon program. If you don't have insurance, a ...
Mass fraction (chemistry) In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. [1] Expressed as a formula, the mass fraction is: Because the individual masses of the ingredients of a mixture sum to , their mass fractions sum to unity:
