Phosphorus-containing compounds are considered as the potential alternatives of traditional inhibitors for suppressing the formation of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs),but the suppression characteristics are scarcely *** this study,ammonium dihydrogen phosphate(ADP)was selected as the inhibitor to inhibit the PCDD/F formation via de novo synthesis at 350℃.The influence of oxygen content and addition method on PCDD/F inhibition was systematically investigated by means of statistical analysis and morphological *** results showed that oxygen enhanced the formation of PCDD/Fs from 1470 ng g^(−1)(9.78 ng I-TEQ g^(−1))to 2110 ng g^(−1)(14.8 ng I-TEQ g^(−1)).ADP significantly inhibited the PCDD/F formation,with inhibition efficiencies ranging from 82.0%to 97.7%.Herein,a higher oxygen content and the premixed way intensified the suppression ***-p-dioxin(DD)/dibenzofuran(DF)chlorination was proven to be effectively suppressed while chlorophenol(CP)route was not obviously *** the addition of ADP,Cl source was significantly reduced and the formation of organic Cl was effectively ***,it decreased the proportion of C–O/C=N and C=O,revealing the efficient inhibition of carbon ***,the formation of copper phosphate and copper pyrophosphate was observed in XPS(X-ray photoelectron spectroscopy)spectra,indicating that the catalytic metal Cu was chelated and passivated by *** premixed way had a better effect on reducing Cl resources,inhibiting oxidation and chelating metals,due to the direct contact with ***,the separation method could only depend on the decomposed gases,resulting in a lower inhibition efficiency.

Furfurylated wood exhibits excellent dimensional stability and corrosion resistance,making it a promising material for constructing buildings,but it is highly ***,flame-retardant furfurylated poplar wood was produced via a two-step process utilizing boric acid(BA)and ammonium dihydrogen phosphate(ADP)as flame-retardant components,and biomass-derived furfuryl alcohol(FA)as a *** acidity of BA and ADP allowed them to catalyze the polymerization of FA,which formed a cross-linked network that immobilized BA and ADP inside the *** addition of BA/ADP substantially delayed the time to ignition from 10 to 385 s and reduced the total heat release and total smoke release by 58.75%and 77.31%,*** of the pyrolysis process showed that the decomposition products of BA and ADP protected the underlying furfurylated wood and diluted combustible *** method significantly improved the fire retardancy and smokeless properties of furfurylated wood,providing promising prospects for its application as an engineering material.

Despite its considerable potential,oil palm trunk(OPT)remains underutilized,largely owing to the cyclical replanting process that occurs every 25–30 *** study aimed to address this issue by developing an ecofriendly oriented strand board(OSB)using vascular bundles(VBs)from oil palm,both in binderless form and with the incorporation of natural adhesives made from sucrose and ammonium dihydrogen phosphate(ADP).The VB was extracted from OPT using a pressure cooker and mixed with a sucrose-ADP solution at various *** mixture was then pressed at temperatures of 180℃ and 200℃ for 10 min to form boards,which were evaluated based on the Japanese Industrial Standard(JIS)A 5908 for *** OSB was also manufactured without the use of any adhesive ***-transform infrared(FTIR)spectroscopy was conducted to evaluate the VB and its *** results indicated that the mechanical properties of the binderless OSB met the JIS A 5908 Type 8 ***,the addition of sucrose-ADP improved the physical and mechanical properties of the board,with an optimal sucrose-to-ADP ratio of 85:*** OSB with the best properties met the JIS A 5908 Type 13 *** FTIR results indicated that carbonyl groups,furan rings,and lignin played important roles in the bonding properties of the *** conclusion,this research demonstrated the potential of VBs as a raw material for producing environmentally friendly OSB,both in binderless form and with the use of sucrose-ADP.
