  2. Phosphite ester - Wikipedia

    en.wikipedia.org/wiki/Phosphite_ester

    The general structure of a phosphite ester showing the lone pairs on the P. In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR) 3. They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite ...

    It also reduces discoloration (yellowing) of plastics. The compound is a phosphite ester formed by the reaction of 2,4-di-tert-butylphenol with phosphorus trichloride. [1] It is an approved food contact materials in the US. [2]

  4. Seed drill - Wikipedia

    en.wikipedia.org/wiki/Seed_drill

    The first known European seed drill was attributed to Camillo Torello and patented by the Venetian Senate in 1566. A seed drill was described in detail by Tadeo Cavalina of Bologna in 1602. [4] In England, the seed drill was further refined by Jethro Tull in 1701 in the Agricultural Revolution. However, seed drills of this and successive types ...

  5. Organophosphate - Wikipedia

    These are primarily the esters of phosphoric acid and can be mono‑esters, di‑esters or tri‑esters depending on the number of attached organic groups (abbreviated as 'R' in the image below). In general man‑made organophosphates are most often triesters, while biological organophosphates are usually mono- or di-esters.

  6. Organophosphorus chemistry - Wikipedia

    en.wikipedia.org/wiki/Organophosphorus_chemistry

    Phosphate esters have the general structure P(=O)(OR) 3 feature P(V). Such species are of technological importance as flame retardant agents, and plasticizers. Lacking a P−C bond, these compounds are in the technical sense not organophosphorus compounds but esters of phosphoric acid. Many derivatives are found in nature, such as ...

  7. Food plot - Wikipedia

    en.wikipedia.org/wiki/Food_plot

    Food plot in Germany. A food plot is a planted area set aside to act as a supplementary food source for wildlife. The term was coined by the U.S. hunting and outdoor industries and food plots are most commonly planted for game species. Food plot crops generally consist of but are not limited to legumes (clovers, alfalfa, beans, etc.), grains ...

  8. Trimethyl phosphite - Wikipedia

    en.wikipedia.org/wiki/Trimethyl_phosphite

    Trimethyl phosphite is an organophosphorus compound with the formula P(OCH 3) 3, often abbreviated P(OMe) 3.It is a colorless liquid with a highly pungent odor. It is the simplest phosphite ester and finds used as a ligand in organometallic chemistry and as a reagent in organic synthesis.

  9. Diethylphosphite - Wikipedia

    en.wikipedia.org/wiki/Diethylphosphite

    Diethyl phosphite is the organophosphorus compound with the formula (C 2 H 5 O) 2 P(O)H. It is a popular reagent for generating other organophosphorus compounds, exploiting the high reactivity of the P-H bond.
