2985-59-3 Usage
Preparation
Preparation by reaction of 1-bromododecane (dodecyl bromide or lauryl bromide) with resbenzophenone in the presence of potassium carbonate in refluxing acetone for 16 h or for 20 h.
Purification Methods
Recrystallise it from n-hexane and then 10% (v/v) EtOH in acetonitrile [Valenty et al. J Am Chem Soc 106 6155 1984].
Check Digit Verification of cas no
The CAS Registry Mumber 2985-59-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,8 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2985-59:
(6*2)+(5*9)+(4*8)+(3*5)+(2*5)+(1*9)=123
123 % 10 = 3
So 2985-59-3 is a valid CAS Registry Number.

Method of purifying arylphenones
-
, (2008/06/13)
Hydroxy and alkyloxy benzophenones, also known as arylphenones, are efficiently and economically purified by contacting them with inorganic phosphorous compounds in the presence of a non-polar solvent. Best results are obtained when the arylphenone is then treated with an activated carbon and/or activated clay.
