摘要:
A-PINENE, B-PINENE, OR TURPENTINE IS ISOMERIZED AT TEMPERATURES RANGING FROM ABOUT 140*C. TO 200*C. IN THE PRESENCE OF A POTASSIUM 13X ZEOLITE-IODINE CATALYST MIXTURE TO YIELD PREDOMINANTLY DIPENTENE AND MINOR AMOUNTS OF TERPINOLENE AND CAMPHENE.
摘要:
ROSIN IS DISPROPORTIONATED AND BLEACHED BY HEATING AT TEMPERATURES OF ABOUT 180-350*C., AND FOR A TIME SUFFICIENT TO REDUCE THE ABIETIC ACID CONTENT TO LESS THAN 15%, IN THE PRESENCE OF 0.01-1% OF AN ARYLTHIOL.
摘要:
TALL OIL PITCH CONTAINING AT LEAST 75% AND PREFERABLY 80% TO 100% OF NONVOLATILE MATERIAL IS INCORPORATED INTO ETHYLENE-PROPYLENE TERPOLYMER RUBBER, PREFERABLY AS A 40% TO 90% SOLUTION IN RUBBER PROCESSING OIL.
摘要:
A CONTINUOUS PROCESS IS DESCRIBED FOR THE ISOMERIZATION OF A-PINENE, B-PINENE, OR TURPENTINE, BY MEANS OF 13X ZEOLITE CATALYST, TO GIVE AN ISOMERIZATE CONTAINING PREDOMINANTLY DEPENTENE AND MINOR AMOUNTS OF TERPINOLENE AND CAMPHENE.
摘要:
IMPROVEMENTS IN WET-PROCESS PHOSPHRIC ACID SYSTEMS COMPRISING ADDING A COMPOSITION COMPRISING (1) AN ADDUCT OBTAINED BY REACTING ETHYLENE OXIDE WITH TALL OIL ROSIN; WITH OR WITHOUT (2) FATTY ACIDS, WHEREBY FOAM IS SUPPRESSED AND GYPSUM CRYSTAL GROWTH IS ENHANCED.
