A method for measuring the deuterium-hydrogen-exchange accessibility of cellulose and of chemically modified cellu luloses, based on the use of D218O and mass spectroscopy, has been applied to a variety of well characterized samples. The expected cor

The chlorination of tung oil was investigated, and certain chlorinated products were screened as plasticizers for polyvinyl chloride resin. Chlorine readily added at low temperatures (0 to 20°C.) as well as at higher temperature (75°C.). The chlori

SUMMARY Five fractions of parenchymatous cells of the cotyledon of the peanut were isolated by homogenization and differential centrifugation from nonaqueous media. These are two protein-rich fractions (one of which appears to be aleurone grains), st

Cellulose formals cellulose-O(CH 2O) n-cellulose were made by reacting purified cotton yarn with formaldehyde in the presence of H218O. Average values for n were determined from the ratio of excess 18O in the formals to formaldehyde bi- functionally
