General Description
Yellowish to amber pellets, powder or flakes or beige powder. Slight odor. Insoluble in water; miscible with ethanol, acetone, benzene, monochlorobenzene, isopropyl acetate, and gasoline.
Reactivity Profile
Accelerated stability studies indicate that Poly(1,2-dihydro-2,2,4-trimethylquinoline) is unstable when stored at 140° F for 2 weeks, protected from light. Acetone solutions are stable for 3 weeks in the dark at room temperature. Solutions in acetone stored for 3 hours open to air and light are also stable. Poly(1,2-dihydro-2,2,4-trimethylquinoline) is incompatible with concentrated nitric acid and strong oxidizers.
Fire Hazard
Poly(1,2-dihydro-2,2,4-trimethylquinoline) is combustible.
Chemical Properties
The pure product is an amber to off-white resinous powder. It is soluble in benzene, chloroform, carbon disulfide and acetone, slightly soluble in petroleum hydrocarbons, and insoluble in water.
Flammability and Explosibility
Nonflammable
Synthesis
Aniline and benzenesulfonic acid were put into a kettle reactor equipped with a condenser device according to the mass parts of 8.9 parts and 0.52 parts, respectively, and heated to melt under stirring and warmed up to 155 ℃, and started to add acetone dr
Toxics Screening Level
The Initial Tlueshold Screening Level (ITSL) for poly(l,2-dihydro-2,2,4 trimethylquinoline), also known as Flectol, is 35 μg/m3 based on a 24-hr averaging time.
