lent to 0.70%. The oil is mobile, brownish yellow in color and has a 

 fresh aromatic odour. When cooled to -5°C. for an hour in a mixture of 

 ice and salt, the oil does not seperate any solid substance. 



A small quantity of the oil was distilled in a flask under atmospheric 

 pressure; it began to boil at about 155°C. and which continued to distill 

 till the thermometer reaches 350°C. and the following fractions were 

 obtained: 155-190= 33%, 190-230°C. 4%, 230-270°C. 4%, 270-310°C. 

 28%, 310-850°C. 23%. 



When bromine was introduced drop by drop, the oil combined with 

 it violently, evolving a large amount of heat and turning into greenish 

 viscous oil. When 2 drops of the oil is dissolved in 1 cc of acetic acid 

 anhydride and shaken with a drop of concentrated sulphuric acid, the 

 liquid assumes an intense green color and becomes very viscous. When a 

 few drops of the oil are introduced in 20 cc of concentrated sulphuric 

 acid, they dissolve for the greater part, and assume a yellowish brown 

 color while a small quantity of deep reddish brown oil floats on it. The 

 oil does not give any characteristic color reaction in presence of dilute 

 ferric chloride. The oil does not reduce ammoniacal silver oxide. The oil 

 neither contains nitrogen nor sulphur, and has the following constants : — 



di,.,,= 0.9217 



{d}^= + 19.29 in 10% chloroform solution. 



N!;= 1.4895. 



Acid value =1.0 



E§ter value=6.56 



Ester value after acetylation= 14.35 



The oil is completely soluble in the ordinary organic solvents. The 

 total quantity of oil used was 454 grams. The oil, after treated with 

 dilute NaaCOs solution, was subjected to fractional distillation under 

 15 mm pressure, a current of CO2 being passed into the liquid to ensure 

 regular ebullition and was separated into the following three fractions: — 



(1) 50°— 100°C. (especially boiled at 56°-62°C) . . 31% 



(2) 100°— 180°C 42% 



(3) 110°— 200°C. (especially boiled at 197°-171°C.) 17%
