Poly(1,2-dihydro-2,2,4-trimethylquinoline) Chemical Properties,Usage,Production
Chemical Properties
Pure product is amber to off-white resinous powder. Soluble in benzene, chloroform, carbon disulfide and acetone, slightly soluble in petroleum hydrocarbons, insoluble in water.
Uses
Antioxidant, stabilizer, or polymerization inhibitor.
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.
Flammability and Explosibility
Non flammable
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 drop by drop, maintaining the temperature at 155??165 ??, and when the addition was completed after 13 parts of mass parts of acetone, the temperature was still maintained at 155??165 ?? to carry on the condensation reaction under the reflux of acetone, and it was carried out until the end point. The product was sent to the distillation tower, evaporated water and recovered acetone, and then carried out decompression distillation, collected 130 ~ 140 ?? (2 kPa) boiling range of the fraction that is the monomer 2,2,4-trimethyl-1,2-dihydroquinoline. In the enamel reactor will first add eight 30% hydrochloric acid, stirring with water diluted to about 17%, heated to 80 ??, Xu drop-added monomer, maintain the temperature 95 ~ 98 ?? for polymerization. After dropping the monomer, continue to react for 4 h. Add 15% NaOH solution for neutralization, so that the reaction material is neutral. Then after cooling, crystallization, filtration, washing and drying, 2,2,4-trimethyl-1,2-dihydroquinoline polymer is obtained.
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.
