It is easy to measure the potential of this system and it has been found that membranes of polystyrene, linseed oil and a tung oil varnish yielded diffusion potentials of 43-53 mV, the dilute solution being always positive to the concentrated. Similar results have been obtained with films of nitrocellulose, cellulose acetate , alkyd resin and polyvinyl chloride . 

Conversion yields in the bienzymatic system have been optimized by using pure substrates (triglycerides) as well as crude vegetable oils (Table 4) rich in a range of polyunsaturated fatty acids (sunflower oil or linseed oil). The use of crude reactants approaches a more realistic scenario for the industrial-scale manufacture of hydropexides. 

Reaction yields depend on the nature of the substrate. Linseed oil contains two polyunsaturated fatty acids 50% linolenic acid and 18% linoleic acid. The corresponding hydroperoxides are obtained with low yields. 

Another pool of ra v materials that up to now has not been considered for the manufacture of biodiesel is highly unsaturated vegetable oils, such as those obtained from linseed or camelina, which give a yield of oil per hectare higher than soybean. 

In varnish manufacture, (he drying oil. i.c.. linseed oil. lung oil. or mixtures of the two. and the resin are cooked together to high temperatures to yield a homogeneous solution for the proper viscosity. The varnish is then thinned with hydrocarbon solvents lo application viscosity. Varnishes were widely used in the nineteenth and early twentieth centuries. They have been replace almost completely by a wide variety uf other products, especially alkyds. epoxy esters, and urethane oils.

In addition to podophyllotoxin itself, closely related compounds, such as 5-methoxypodophyllotoxin (3.89), can be used as a precursor for anti-cancer drugs. Linum species (flax, linseed) can produce podophyllotoxin or substituted podophyllotoxins in tissue culture with yields of up to 0.35% of dry weight. The biosynthesis of 5-methoxypodophyllotoxin in Linum flavum was investigated by Xia et al. (2000), whereas Seidel et al. (2002) investigated podophyllotoxin (3.86) production in cell cultures of Linum album.

Biodiesel made from feedstocks containing large concentrations of long-chain saturated fatty acids will have very poor cold flow properties. Less expensive feedstocks such as palm oil or tallow (see Table 1.3) may not be feasible in moderate temperature climates. In contrast, feedstocks with lower concentrations of long-chain saturated fatty acids yield biodiesel with more attractive cold flow properties. For example, biodiesel from canola, linseed, olive, rape-seed, and safflower oils have CP and PP close to or below 0°C (Table 1.3). 

Platinum hydrosol also catalytically assists in the reduction or hydrogenation of many organic substances such as unsaturated oils. To this end an aqueous solution of colloidal platinum is added to an alcoholic solution of the organic substance and hydrogen gas bubbled through. The temperature, pressure, and extent of agitation of the liquid are important factors. In this manner linseed and other oils are readily reduced, saturated or hardened, to yield white fatty substances.8...
