Resin dried

Processing is similar to other engineering plastic resins. Drying is necessary before extmsion or molding. Special drying precautions are required for PET products to prevent degradation and splay.

In recent years, capillary electrophoresis (CE) has been introduced as an alternative method for performing a chromatographic analysis of art objects, and thus, a number of methods for analysis of waxes, resins, drying oils, animal glues, and plant gums have been proposed [49]. 

The lignins were separately mixed with PF resin (dry blending) at 30% and 50% levels prior to application as a binder. The formation and testing (9) of the waferboards (30 cm x 30 cm) were done by the Alberta Research Council Panel Testing Laboratory. 

The synthesis of 3 was carried out as described above with the exception that Boc-Lys(Fmoc)-OH was used in the synthesis in place of Boc-Lys(CHO)-OH (Scheme 4). Following completion of the peptide synthesis, the peptide-bound resin 6 (250 mg) was treated with piperidine/DMF (20 80, 20 mL) for 20 min, the solvent removed by filtration, and the resin washed with CH2C12(3 x 20 mL). DMF (5mL) was added to the resin followed by a CH2C12 soln (5 mL) of formic anhydride, prepared as above, and DIPEA (350 xL, 1 mmol). The resin was shaken for 20 min, the solvent removed by filtration, and the formylation repeated by the addition to the resin of DMF (5 mL), a CH2CI2 soln of formic anhydride (5 mL), and DIPEA (350 pL, 1 mmol). The resin was shaken for 15 min, filtered, washed with CH2C12 (3 x 20 mL), and the resin dried under vacuum to yield 3. The peptide-resin was converted into 4 by treatment with HF as described above.

Apply gentle suction to the flask and collect the filtrate. Use the filtrate to rinse all the resin into the column, and when all is transferred suck the resin dry for 5 minutes. 

Sometimes a resin manufacturer will list a value for sphericity which is the percentage of perfectly spherical beads in a resin sample as determined by a technique based on allowing resin, dried to a free flowing condition, to roll down an inclined surface. 

Procedures bearing some similarity to the Philippou process were patented by Emerson in 1953 and 1963 104, 105). The first patent consisted of pretreatment of lignocellulosic particulate material with urea (0.7-11%), followed by addition of furfural (0.8-16%) and an acid or acid salt catalyst (1.0-16%), and pressing at elevated temperatures. The second involved a mixture of urea, furfural, lignin, petroleum resin, drying oil, wax, and an oxidation catalyst as a cross-linking mixture.

Recent examples, for instance, of the catalytic application of the commercially available macroporous Amberlyst-15 include the Michael addition of pyrroles to a,P-unsaturated ketones (Scheme 10.4) [48]. In this process, the acid ion exchange resin (dry, 10% w/w) allows on to obtain mono and dialkylated pyrroles 5 and 6 in reasonable yields. Similarly, this catalyst (dry, 30% w/w) can catalyze the aza-Michael reaction of amines with a,P-unsaturated ketones, esters and nitriles to afford 7 in 75-95% yields under solvent-free conditions. Interestingly, yields were significantly lower using typical solvents such as DCM (dichloromethane), CH3CN, THF, DMF or EtOH [49], Recycling the catalyst is possible in both cases, but a smooth decrease in the yield is observed for each new run. 

Originally based on linseed oil other oils have included tung, dehydrated castor oil and various resins. Drying action involves resinification by atmospheric oxidation. Drying can be accelerated by the addition of certain metals (lead, cobalt, manganese) as driers. Time to dryness may be a few hours to a matter of seconds.
