The Action of Concentrated Sulfuric Acid on Olefins, With Particular Reference to the Refining of Petroleum Distillates.

Abstract

after a 6-day fast weighed 1600 g. gen whatever was found in the liver. of the carbohydrates in the litchi nut. The animal was killed and no glyco-'l'hese results show in a most marked way the glycogenetic properties SEW HAVEN, CONN.

Determination of Total Aromatic Plus Olefin

“…In the analysis of dicyclopentadiene concentrates of the order of 50 to 80% purity, accuracy of the order of 1 or 2% may be obof hydrocarbon mixtures (7,8,10). Fisher and Eisner (8) have shown that adjustment of acid concentration and experimental conditions to overcome this failing has not been entirely successful.…”

Approximate determination of olefin and aromatic hydrocarbons

“…As has been stated in the literature (1), several types of reaction. take place between sulfuric acid and olefinsnamely, esterification, alcohol formation, oxidation, polymerization, and condensation with aromatic hydrocarbons when the latter are present.…”

Reactions of Cyanogen Chloride. Ii. Amines From Cyanogen Chloride and Olefins

“…Moreover, an excess of cyanogen chloride ought to aid in obtaining a higher yield of amine. Actually, adding cyanogen chloride to the alkyl hydrogen sulfate lowered the yield by one-half (Run 8) while an 100% excess of cyanogen chloride (Run 12) did not materially increase the yield (Table III).…”

“…The material balance was quite low in most cases where attempts were made to evaluate the recovery, especially where some reaction did occur. This is believed to be a result of the formation of considerable amounts of stable water-soluble sulfuric acid esters, which are known to be stable up to boiling temperatures in aqueous solutions (12).…”
