Residual monomers in the latex are avoided either by effectively reacting the monomers to polymer or by physical or chemical removal. The use of tert-huty peroxypivalate as a second initiator toward the end of the polymeri2ation or the use of mixed initiator systems of K2S20g and tert-huty peroxyben2oate (56) effectively increases final conversion and decreases residual monomer levels. Spray devolatili2ation of hot latex under reduced pressure has been claimed to be effective (56). Residual acrylonitrile also can be reduced by postreaction with a number of agents such as monoamines (57) and dialkylamines (58), ammonium—alkali metal sulfites (59), unsaturated fatty acids or their glycerides (60,61), their aldehydes, esters of olefinic alcohols, cyanuric acid (62,63), andmyrcene (64). 

Although not very commonly used in the separation of nentral hpids, two-dimensional systems have been nsed to separate hydrocarbons, steryl esters, methyl esters, and mixed glycerides that move close to each other in one-dimensional systems. Complex neutral lipids of Biomphalaria glabrata have been first developed in hexane diethyl ether (80 20), dried, and the plates have been turned 90°, followed by the second development in hexane diethyl ether methanol (70 20 10) for complete separation of sterol and wax esters, triglycerides, free fatty acids, sterols, and monoglycerides [54]. 

The range of hydrophobes present may also be unexpectedly broad, since the raw materials often consist of mixtures of symmetrical and/or mixed glycerides. As little as 60% of an oil may be sulphatable sulphation is never carried to theoretical completion and is often far below 100%. With these provisos in mind, the chemistry of the sulphated oils can be...

The iodine value is reported as the number of grams of iodine that bind to 100 g of sample. As such, the IV can only be used as an index of unsaturation, especially in a mixed triacyl-glyceride system. This means that it can be compared to the same data from other mixed triacylglyceride systems, i.e., comparing to a competitor oil/fat. The other possible use is to reflect changes in the value based on treatment effects occurring in the system in question, e.g., to monitor hydrogenation. 

Partial (Semi) Synthesis. A blend of two methodologies can be used quite effectively to prepare mixed acid phosphatidylcholines, which are of prime importance in elucidating the structure of naturally occurring phospho-glyceride and phospholipase A2 activity. Perhaps the best scenario would be to illustrate the activity of the phospholipase A2 (from Crotalus adamanteus snake venom) toward a racemic phosphatidylcholine sample and toward individual sn-1 and sn-3 enantiomers. In each case the same result would be found, and so only the racemic mixture reaction is depicted in Figure 4-8. 

Monotectic mixtures arise when the individual components have similar melting points, molecular volumes and polymorphic forms. Figure 17.12(a) represents a possible phase diagram for monotectic mixtures. A typical monotectic solution occurs when SSS is mixed with SOS. Lutton (1955) determined that the a form was present and associated with limited solid solution formation, and contrasted with the a forms of other glyceride mixtures that formed continuous solid solutions (Rossell 1967). It was found, for this system, that tristearin incorporates about 50% of the SOS into a solid solution on the other hand, SOS incorporates very little SSS into a solid solution. 

Peritectics are observed in mixed saturated-unsaturated systems. Figure 17.12(c) is a theoretical peritectic phase diagram. Several authors have reported mixtures of SOS and SOO to exhibit peritectic behavior (Rossell 1976). The peritectic mixture contained 24%SOS melted at 27.4°C, determined using differential thermal analysis. Table 17.4 list common phase behaviors of binary mixtures for different triacyl-glycerides adapted from Rossell (1967).
