Cure of alkyd resin A varnish is prepared by mixing 100 g of the alkyd resin prepared above, 0.05 g of Co(II) 2-ethylhexanoate, 0.05 g of calcium 2-etliyl-hexanoate, and 0.02 g of lead 2-ethylhexanoate. This mixture is held for 24 h in a closed flask before use. A thin layer of this varnish, applied on a metal plate, forms a hard, glossy coating after 24 h drying at room temperature. 

The third general classification of solution synthesis approaches used for inorganic electronic thin film fabrication is referred to as metallo-organic decomposition, or MOD for short.23-29,37,38,85 Historically long-chain carboxylate compounds, such as lead 2-ethylhexanoate, zirconium neodecanoate, and titanium di-methoxy di-neodecanoate have been used.23-29,85 Both commercially available precursors and in-house synthesized starting reagents have been used. 

Activators. Activators are chemicals that increase the rate of vulcanization by reacting first with the accelerators to form mbber soluble complexes. These complexes then react with the sulfur to achieve vulcanization. The most common activators are combinations of zinc oxide and stearic acid. Other metal oxides have been used for specific purposes, ie, lead, cadmium, etc, and other fatty acids used include lauric, oleic, and propionic acids. Soluble zinc salts of fatty acid such as zinc 2-ethylhexanoate are also used, and these mbber-soluble activators are effective in natural mbber to produce low set, low creep compounds used in load-bearing applications. Weak amines and amino alcohols have also been used as activators in combination with the metal oxides. 

Short sections of thin metal wires (good conductor of heat) such as , Pb, Al, Cu, Ag and Mo Increase burn rates of DB propellants containing ballistic modifiers such as lead salts of salicylic and 2-ethylhexanoic add without any adverse effect on the plateau region [240]. 

The deposited gel is then dried in a suitable atmosphere and at an appropriate temperature. For example, a ferroelectric PZT film can be made by dipping a silica substrate into a hydrolyzing mixture of titanium tetraiso-propoxide (0.48 mol), zirconium tetra-n-propoxide (0.52 mol), and lead(II) 2-ethylhexanoate (1.0 mol), drying the film at 100 °C, firing it at 400°C, repeating the procedure 20 times, and then finally firing the sample at about 600 °C. 

The rates at which nonconjugated drying oils dry are slow. Metal salts (driers) arc known to catalyze the drying rate. The most widely used are the oil-soluble cobalt, manganese, lead, zirconium, and calcium salts of 2-ethylhexanoic acid or naphthenic acids. See also Paints and Coatings. 

Zinc 2-ethylhexanoate was prepared in refluxing toluene from the reaction of 2-ethylhexanoic acid with zinc oxide. The lead salt was prepared in methanol by the reaction of lead acetate with 2-ethylhexanoic acid. The reaction of barium oxide with 2-ethylhexanoic acid in toluene provided the barium salt. 

At lower temperature the equilibrium is shifted in favor of the allophanate but the rate of equilibrium decreases and at room temperature no reaction occurs in 2 weeks. Metal carboxylates (naphthenates, 2-ethylhexanoates, linoresinates of Pb, Co, Cu, Mn, Fe, Cd, V, Zn) were found to accelerate this reaction very appreciably. Particularly active are the lead and cobalt salts which caused complete conversion at room temperature in a few hours. All the metal salts with the exception of the zinc salts also catalyze the... 

The introduction of the trimethylsilyl chloride trapping technique" led to improved yields in the case of simple aliphatic esters. The initial silylated products are easily isolated and can be converted into the acyloins simply and in high yield. For simple aliphatic esters the yields are in the range 56-92%. Use of trimethylsilyl esters, rather than simple alkyl esters, leads to faster reactions, but lower yields.Substituted esters which have been successfully used in the newer procedure include ethyl 2-ethylhexanoate (83%), ethyl trimethylsilylacetate (90%)," ethyl 3-trimethylsilylpropionate (65%)," ethyl phenylacetate (48%)," ethyl 3-phenylpropionate (79%)" and 2-(2-methoxycarbonylethyl)-2-methyl-l,3-dioxolane derived from levulinic acid (65%)." In the case of ethyl adamantane-l-carboxylate the yield using the newer procedure is reported to be inferior to that using the earlier procedure. 

As discussed above, differences in reactivity ratios can lead to drift in the copolymer composition from that of the starting materials. Noel et al. [39] studied a unique set of monomers, namely VAc, vinyl 2,2-dimethylpropionate and vinyl 2-ethylhexanoate, and determined their reactivity ratios with methyl acrylate. Their work led to the conclusion that the three vinyl esters can be described with one set of reactivity data. This greatly simplifies any potential for compositional drift since only one variable must now be dealt with, namely interphase partitioning of the monomer. Copolymers or terpolymers produced with VAc and vinyl esters have the potential to outperform VAc/acrylic copolymers due to the mote random copolymerization of VAc with other vinyl ester monomers compared with acrylic monomers [40], as is discussed in Section 16.9.
