Thermal Degradation Products of THPOH-NH3 Treated Cotton
Abstract
The controlled pyrolysis of a particular flame retardant treated cotton fabric has been examined and the chemical composition of several main pyrolysis products have been investigated. Treated cotton fabric (VEE 4253/ THPOH-NH3 process) was pyrolyzed under controlled laboratory conditions and the thermolysis products were investigated. The amount of volatilized products ranged from 50 to 60% and consisted of an unusually large proportion of solid material. This material was found to contain levoglucosan along with polymeric substances presumed to orginate from incomplete degradation of the flame retardant polymer. The liquid portion of the pyrolysis product was separated into components, which were characterized by GC, GC-FTIR and NMR. Positive identification was made for levoglucosenone, 2-furaldehyde, 5-methyl-2- furaldehyde, and 2-furyl methyl ketone. Several additional components were tentatively identified. The composition of the pyrolyzate from this particular fire retardant treated cotton materials. The potential toxicity of the components are briefly discussed.
