[1] [2] [3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name ; the letter following denotes the variant, which depends on the additional substituents.
In organic chemistry, a bisthiosemicarbazone is a derivative from an elimination reaction between a thiosemicarbazide and a diketone. Their structure is H 2 NHC(=S)NN=C(R 1)−R 2 −C(R 3)=NNHC(=S)NH 2. A 'thiosemicarbazone' contains a sulfur atom in lieu of the ketonic oxygen in semicarbazone.
[2] [7] BPA is produced on an industrial scale by the condensation reaction of phenol and acetone. Global production in 2022 was estimated to be in the region of 10 million tonnes. [8] BPA's largest single application is as a co-monomer in the production of polycarbonates, which accounts for 65–70% of all BPA production.
The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').
-bis, an IUPAC numerical multiplier for compound or complex features, meaning 2; A colloquial name for N,N'-Methylenebisacrylamide; Barratt Impulsiveness Scale, in psychology; Behavioural Inhibition System, a brain-behavioral systems in reinforcement sensitivity theory; BIS monitor or bispectral index, to assess the depth of anaesthesia
Bis(2-ethylhexyl) phthalate (di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers.
1,1-Bis(diphenylphosphino)methane (dppm), is an organophosphorus compound with the formula CH 2 (PPh 2) 2. Dppm, a white, crystalline powder, is used in inorganic and organometallic chemistry as a ligand. [1] It is more specifically a chelating ligand because it is a ligand that can bond to metals with two phosphorus donor atoms.
Disiamylborane (bis(1,2-dimethylpropyl)borane) is an organoborane with the formula [((CH 3) 2 CHCH(CH 3)) 2 BH] 2 (abbreviation: Sia 2 BH). It is a colorless waxy solid that is used in organic synthesis for hydroboration–oxidation reactions. Like most dialkyl boron hydrides, it has a dimeric structure with bridging hydrides.
