1,4-Cyclohexanedione is an organic compound with the formula (CH 2) 4 (CO) 2. This white solid is one of the three isomeric cyclohexanediones . This particular diketone is used as a building block in the synthesis of more complex molecules.
The SH-4 is a RISC CPU and was developed for primary use in multimedia applications, such as Sega's Dreamcast and NAOMI game systems. It includes a much more powerful floating-point unit and additional built-in functions, along with the standard 32-bit integer processing and 16-bit instruction size. SH-4 features include:
1,4-butane sultone is a six-membered δ-sultone and the cyclic ester of 4-hydroxybutanesulfonic acid.As a sulfo-alkylating agent, 1,4-butanesultone is used to introduce the sulfobutyl group (–(CH 2) 4 –SO 3 −) into hydrophobic compounds possessing nucleophilic functional groups, for example hydroxy groups (as in the case of β-cyclodextrin [1]) or amino groups (as in the case of ...
1,4-Dioxane (/ d aɪ ˈ ɒ k s eɪ n /) is a heterocyclic organic compound, classified as an ether. It is a colorless liquid with a faint sweet odor similar to that of diethyl ether . The compound is often called simply dioxane because the other dioxane isomers ( 1,2- and 1,3- ) are rarely encountered.
1,4-Dimethylnaphthalene (1,4DMN) is a plant growth regulator that occurs naturally in potato tubers, preventing them from sprouting. [1] Synthetic forms such as 1-4SIGHT are applied to potatoes during storage. [2] Although discovered in the 1970s, it was not used commercially in the USA until 1996 [3] and in Europe until the 2010s. [4]
1,4-Cyclohexanedimethanol diglycidyl ether is an organic chemical in the glycidyl ether family. [2] Its formula is C 14 H 24 O 4 and the IUPAC name is 2-[[4-(oxiran-2-ylmethoxymethyl)cyclohexyl]methoxymethyl]oxirane. It has the CAS number of 14228-73-0 [3] and is REACH registered in Europe. [4]
Concept art of MiG 1.44 in flight. The MiG 1.44 had its origins in the early 1980s, when the U.S. Air Force began developing a successor to the F-15 Eagle under the Advanced Tactical Fighter (ATF) project, which would eventually result in the supermaneuverable and stealthy, albeit costly, F-22 Raptor that first flew in 1997.
The first step is the liquid- or vapour-phase chlorination of butadiene to a mixture of 3,4-dichlorobut-1-ene and 1,4-dichlorobut-2-ene (both isomers). In the second step, the mixture of 1,4-dichlorobut-2-ene and 3,4-dichlorobut-1-ene is isomerized to 3,4-dichlorobut-1-ene by heating to temperatures of 60–120 °C in the presence of a catalyst.
