Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F).

At the time of launch, Microsoft deemed Windows 7 (with Service Pack 1) and Windows 8.1 users eligible to upgrade to Windows 10 free of charge, so long as the upgrade took place within one year of Windows 10's initial release date. Windows RT and the respective Enterprise editions of Windows 7, 8, and 8.1 were excluded from this offer.
N-Oleoylsarcosine can be obtained in the reaction of oleic acid, N-methylglycine and its sodium salt at 170 °C for 8 to 10 hours upon elimination of water. [ 2 ] More gentle conditions (120 °C) and shorter reaction times (3.5 hours) can be used when methyl oleate is reacted with sodium N -methylglycinate upon the addition of equimolar amounts ...
The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and even up to a million for some products. PolyDADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%. It is a high charge density cationic polymer.
Methylethyl ketone oxime is the organic compound with the formula C 2 H 5 C(NOH)CH 3.This colourless liquid is the oxime derivative of methyl ethyl ketone. MEKO, as it is called in the paint industry, is used to suppress "skinning" of paints: the formation of a skin on paint before it is used.
Vinyltriethoxysilane is an organosilicon compound with the formula (C 2 H 5 O) 3 SiCH=CH 2. It is a colorless liquid. The compound is bifunctional, featuring both a vinyl group and hydrolytically sensitive ethoxysilyl groups. As such it is a crosslinking agent. [1]
The mechanism begins by generation of Si(CH 3) 3 X and a highly reactive [CF 3] − (trifluoromethide) intermediate. The [CF 3 ] − attacks the carbonyl to generate an alkoxide anion. The alkoxide is silylated by the reagent to give the overall addition product, plus [CF 3 ] − , thus propagating an anionic chain reaction.
Isobornyl cyclohexanol (IBCH, Sandenol) is an organic compound used primarily as a fragrance because of its aroma which is similar to sandalwood oil.Its chemical structure is closely related to that of both α-santalol and β-santalol, [4] which are the primary constituents of sandalwood oil.
