As temperature increases, the weight of cracking reactions (yielding benzenes or naphtalenes) becomes more important, increasing the catalyst's stability, although new polyaromatic carbon species are detected. A new strategy to minimize the deactivation caused by this compound, consisting of co-feeding...
Correlation of Structure of Benzofuranones with Proceesing Stability; 苯并呋喃酮类抗氧剂结构与加工稳定化作用的关系研究 2. Irganox HP-136(3-arylbenzofuranones)have been found to be fast acting radical scavengers,which can efficiently trap carbon-centered radicals. Irganox HP-136(3芳-基-苯...
SECTION 10: Stability and reactivity 10.1 Reactivity The substance slowly polymerizes at ambient temperatures. The substance more rapidly polymerizes under the influence of heat and under the influence of acidic catalyst. 10.2 Chemical stability no data available 10.3 Possibility of hazardous reacti...
of course, other additives such as antioxidants, e.g. above phenols, and U.V. absorbers are also employed together with the compounds of formula Ic, the polymeric material has an enhanced long term stability against thermal- and photoxidative degradation....
The stability of the molecular packing in 3-mesityl-3-methylcyclobutyl 3-methylnaphtho[1,2- b ]furan-2-yl ketone, C 28 H 28 O 2 , (III), arises from C—Hπ and π–π stacking interactions. The fused naphthofuran moiety in (III) is essentially planar and makes a dihedral angle ...
Non-covalent interaction between dietary stilbenoids and human serum albumin: Structure-affinity relationship, and its influence on the stability, free radical scavenging activity and cell uptake of stilbenoids 2016, Food Chemistry Citation Excerpt : Natural stilbenoids are typically non-flavonoid polyphenols...
The result obtained from the quantitative structure-activity relationship study of these compounds shows that the models have significant predictive power and stability, as shown by statistical parameters such as R(2), Q(2), R(2)(pred), R(2)(m), F-value, Durbin-Watson, variable inflation ...
Multilayered coated liposomes were prepared using the layer-by-layer (LbL) technique in an effort to improve their stability in biol. media. The formulation strategy was based on the alternate deposition of two biocompatible and biodegradable polyelectrolytes – poly(L-lysine) (PLL) and poly(L-gl...
