Trimethyl phosphate is a mild methylating agent, useful for dimethylation of anilines and related heterocyclic compounds. [2] The method is complementary to the traditional Eschweiler-Clarke reaction in cases where formaldehyde engages in side reactions.
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.
It is under supervision of Bangladesh Chemical Industries Corporation (BCIC). It primarily produces phosphate fertilizers . [ 1 ] [ 2 ] The factory complex consists of 2 units of TSP fertilizer producing facility with installed capacity of 1,52,000 MT (Unit-1; 32,000 MT and Unit-2; 1,20,000 MT).
Trimethylphosphine is a highly basic ligand that forms complexes with most metals. As a ligand, trimethylphosphine's Tolman cone angle is 118°. [7] This angle is an indication of the amount of steric protection that this ligand provides to the metal that to which it is bound.
Phosphites are oxidized to phosphate esters: P(OR) 3 + [O] → OP(OR) 3. This reaction underpins the commercial use of some phosphite esters as stabilizers in polymers. [6] Alkyl phosphite esters are used in the Perkow reaction for the formation of vinyl phosphonates, and in the Michaelis–Arbuzov reaction to form phosphonates.
Dimethyl methylphosphonate can be prepared from trimethyl phosphite and a halomethane (e.g. iodomethane) via the Michaelis–Arbuzov reaction. [2]Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons.
In 1982, it set up the first tiles factory in Bangladesh. [10] It is subsidized by Bangladesh government. [11] The Training Institute for Chemical Industries (TICI) is a sister concern of BCIC and is run by BCIC too. [12] Chittagong Urea Fertilizer School and College falls under this corporation, [13] as does Urea Sar Karkhana School & College ...
Its shareholders include Government of Bangladesh, Bangladesh Chemical Industries Corporation (BCIC), and private sectors of Japan, Denmark and Netherlands. [2] It is an export oriented factory and one of two major fertilizer factories in Bangladesh. [3] [4]
