CRUDE SOYA OIL IH AlKYDS
Phis report covers work done at the request of Engineering Service to dot ermine whether satisfactory alkyds could be made from crude soya oil by using Adsorb! Clay throughout the. resin cook*
Conclusions:
1,; Gelation -difficulties are normally encountered la the preparation jef crude oil resins because the impurities in the oil prevent the preparation of a proper monoglyoerid* Phis can be remedied by substitution of about .1,5# G-218 (based on the oil) for the usual 0,1# G*2lB monoglyceride catalyst.
2. Resins .made with and without 3$ Adsorbol Clay arc practically identical in final constants* Such resins, although substantially normal in other properties, are much darker ih color (5*2 e compared to 3.2) than those made from alkali refined oil under the best conditions.
3. In manufacture of resins from crude oil, the follow*' lag additional points need to be considered, (a) impurities in tho oil will result in-a loss of about 5# of the oil by precipi tation during the cook, fb) these-impurities may char- and clog heat exchangers, and (c) they may, because of their gelatinous nature, cause filter pressing troubles.
Experimental:
Resins of tho RC-453 type were made from (a) B-59, (b) crude- soya end (c) crude soya with 3# Adsorb! Clay (on.resin solids) present during entire opok* Comparisons of the Solution properties of these resins were made.
