Propyleneoxide(PO) can be produced by the conventionalchlorohydrinorhydroperoxideprocess. In the chlorohydrin process,propyleneis reacted with chlorine and water to form propylene chlorohydrin, which is converted toPOwith sodium orcalcium hydroxide, forming a large amount of valueless chloride salt simultan...
It was found that, when 3,3,3-trichloropropene reacts with phenol in presence or absence of aluminum chloride, a mixture of HOC 4 H 4 CH 2 CH = CCl 2 and p-HOC 2 H 4 CH 2 CH = CCl 2 is formed. When the condensation is carried out with sodium phenoxide in an alcoholic ...
Comparison is made with the adducts from the addition of 2,4-dinitrobenzeneselenenyl chlorides. β-Chloroalkyl 2,4-dinitrophenyl selenides react with chlorine or sulfuryl chloride to yield β-chloroalkyl 2,4-dinitrophenyl selenide dichlorides. β-Chloroalkyl selenide dichlorides were observed to ...
2,3-Dichloropropene (CAS 78-88-6) is a colorless liquid with a strong, sweet odor. It has a basic structure consisting of two chlorine atoms attached to a propene molecule. This chemical is sparingly soluble in water, but it can dissolve in organic solvents such as ethanol and ether. It...
CIS-1,3-DICHLOROPROPENE, with the chemical formula C3H4Cl2 and CAS registry number 10061-01-5, is a compound known for its applications in agriculture and industry. This colorless liquid, also referred to as cis-1,3-dichloropropylene, is characterized by its two chlorine atoms attached to a...
Because the molecular structure contains active chlorine atoms and epoxy groups, it is chemically active. When hydrolysis, α-chloroglycerin is first generated, and then glycerin is generated. It can undergo a ring-opening reaction, which can produce propylene glycol and glycerol; it can react ...
An early explanation for the latter phenomenon (Armstrong et al., 1967) suggested that because the replacement of the chlorine atom on atrazine with a hydroxyl group raises the pKa of the substituted amino groups on the molecule, this also increases its tendency to form hydrogen bonds with soil...
Vapors may form explosive mixturewith air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep awayfrom alkaline materials, strong bases, strong acids, oxoacids,epoxides, peroxides, ...
activation of the magnesium dihalide; thereafter, the milled product is treated one or more times with an excess of TiCl4 at a temperature ranging from 80° to 135°C, and then washed repeatedly with a hydrocarbon (hexane, for example) until no more chlorine ions can be found in the ...
reactants should be employed such as anisole, phenol, etc. and the temperature and time of reaction should be increased. Similarly, with the first and second stage reactions, equimolar amounts of the aryl reactant should be employed, because the driving force of a molar excess is not ...
