“…Comparing Figure 4 with 5, we can see both untreated and treated wool, the N-H bending frequency at 1520 cm À1 shows a reduction in intensity, as would be expected with increasing loss of ammonia from the char; the CH 2 -and CH 3 -stretching at 2950 and 2924 cm À1 do not show much reduction in intensity until 400 C, indicating that the evolution of volatile hydrocarbons commences only at higher temperatures [9,10].…”

The thermal degradation of wool treated with the flame retardant synergistic system, potassium hexafluorotitanate and dicarboxylic acids, was studied by thermal analysis, mass loss, the limiting oxygen index (LOI) and infrared spectroscopy. The wool treated with the flame-retardant reagents show decrease in the temperature of decomposition and mass loss, increase in LOI, and changes in activation energy, comparing with the untreated wool.

Practical interest in effects of heat on wool focuses on increasing its resistance to heat and combustion and on decreasing possible hazards from decomposition products. In our laboratory we use two strategies to develop practical wool products with enhanced flame resistance. The first is direct chemical combination with flame-retardants. 'I'wo treatments of this first type use bis(β-chloroethyl)vinyl phosphonate in aqueous solution and chlorendic anhydride in dimethylformamide. An example of the second strategy, used with the nonreactive flame-retardant tris(2,3-dibromopropyl)phosphate, is to mix this compound with a polyurethane prepolymer, which is then anchored to the wool surface by interfacial polymerization. The resulting fabric shows significantly increased flame-resistance as well as durable resistance to laundering shrinkage. These and other empirical finishing treatments reported to impart flame-resistance to wool are critically reviewed. Areas for future research are noted with emphasis on evaluating the safety of treated fabrics for potential users.

“…Next, the solvent effect was investigated on the model reaction, and different solvents such as H 2 O, DMF, CH 3 COOEt, and EtOH were utilized to maximize the efficiency. A mixture of H 2 O:EtOH in 1:1 ratio could afford the best result (Table 1, entries 3, [12][13][14][15][16]. The efficacy of the base on the reaction was also checked.…”

In this study, magnetic nitrogen-doped carbon (MNC) was fabricated through facile carbonization and activation of natural silk cocoons containing nitrogen and then combined with Fe 3 O 4 nanoparticles to create a good support material for palladium. Palladium immobilization on the support resulted in the formation of magnetic nitrogen-doped carbon-Pd (MNC-Pd). The prepared heterogeneous catalyst was well characterized using FT-IR, TGA, EDX, FE-SEM, XRD, VSM, and ICP-OES techniques. Thereafter, the synthesis of biaryl compounds was conducted to investigate the catalyst performance via the reaction of aryl halides and phenylboronic acid. Further, the catalyst could be used and recycled for six consecutive runs without any significant loss in its activity.
