Extraction of natural rubber and resin from guayule using an accelerated solvent extractor
Industrial Crops and Products, 2013Abstract Accelerated solvent extraction is a relatively rapid automated method for extracting compounds of interest from plant materials. We have developed a sequential solvent extraction method that can be used to accurately quantify the rubber and resin in samples of guayule ( Parthenium argentatum Gray), a new industrial crop now in commercial ...

Post-harvest storage effects on guayule latex, rubber, and resin contents and yields
Industrial Crops and Products, 2009Guayule is a new crop being commercialized for hypoallergenic latex production. Because natural processes that occur in the plant following harvest, notably dehydration, result in rapid loss of latex and immediate processing of guayule shrub for latex on a commercial scale is not feasible, storage conditions that maintain latex concentration and yield ...

Degradative Effects of Guayule Resin on Natural Rubber. II. Kinetic Studies
Rubber Chemistry and Technology, 1982Abstract Qualitative studies reported earlier and the kinetic studies reported here indicate that the unsaturated fatty acids in guayule resin are primarily responsible for the ability of guayule resin to accelerate the oxidative degradation of natural rubber.

Conversion of guayule resin to C1-C10 hydrocarbons on zeolite based catalysts
Fuel, 1992Abstract The conversion of guayule resin to C 1 -C 10 hydrocarbons, using different zeolite based catalysts, has been studied. HY, CaHX and HZSM-5 zeolites and a silica-alumina amorphous matrix were tested. The best results were obtained with a physical mixture of 70 wt% HZSM-5 zeolite ( Si Al = 13 ) and 30 wt% silica-alumina amorphous ...

Effect of resin components on the degradation of guayule rubber
Journal of Applied Polymer Science, 1985AbstractAll natural rubbers are likely to contain some long chain fatty acids or their esters. The individual effect of the four C18 fatty acids (stearic, oleic, linoleic, and linolenic acid) present in the guayule resin on the degradation of guayule rubber has been investigated concurrently by stress–relaxation of radiation cured rubber networks and ...

Gravimetric Analysis for Determining the Resin and Rubber Content of Guayule
Rubber Chemistry and Technology, 1983Abstract The method presented provides a fast and sufficiently accurate method for determining the resin and rubber contents of guayule. Although it does not provide definitive or “absolute” values that presumably can be obtained with sophisticated instrumentation, it is well suited for agronomic developmental studies at the field station level.

Rubber and Resin Yield Performance of New Guayule Selections
Agronomy Journal, 1992AbstractGuayule (Parthenium argentatum Gray) is a promising alternative to the rubber tree (Hevea brasiliensis Muell. Arg.) for domestic production of natural rubber in semiarid regions. Guayule is not yet a crop and its commercialization will depend on the development of high rubber‐yielding cultivars. The objectives of this study were to determine if
