The sulfur content is somewhat higher and the distillation range somewhat wider than usual. However, the quantity received was small and had a minimal effect on cyclohexane production.

COMMENTS:
With reference to sample No. LC 72-66, we believe the lack of better agreement between Lake Charles and Ponca City laboratories is due to too large a sample being used at Lake Charles.

C-192-66 3-25-66 Page 2
The excellent agreement in weight percent benzene results at Ponca City by the freezing point and chromatographic methods represents the kind of check which should be expected from these two procedures.
With reference to sample No. LC 107-66, it is impossible to analyze this sample properly by using a chromatographic method which employs only a "boiling point" column, such as paraffin oil. This type column will not separate the olefins which a^re present from the benzene. In order to make this separation, a substrate with a great deal of aro matic selectivity must be employed. The best known materials used for this purpose are the .Carbo^axes.
Another danger in an analysis of this type is overloading of the detector with the major component (i.e., too large a sample.) Too large a quantity of the major components entering the detector causes a loss of linearity of response. This may be guarded against by analyzing a sample of known purity for reference. Care should be ta.ken to use the same sample size in analyzing the unknown sample as was used with the reference sample.
P.C. analysis of L.C. No. 107-66 shows that virtually all of the known C_ paraffins and cycloparaffins are present. Thus, each one of the peaks on the Lake Charles chromatogram probably represents several components, and individual component identification is impossible. Ob viously then, this is further evidence that the paraffin oil column is entirely inadequate.
It is true that the carbonwax column recommended by the Ponca City laboratory also has limitations with reference to complete separation, but it does give reliable values for benzene and toluene which are of primary interest.

DODECYL BENZENE AND DODSCYL BENZENE INTERMEDIATE AS NO. 2 HEATING OIL COMPONENTS - BALTIMORE PETROCHEMICAL PLANT
Samples of dodecyi benzene (D.B.) and dodecyi benzene interme
diate (D.B.I.) were received from the Process Laboratory to aetenaine how much of a 60-40 by weight, D.B.-D.B.I. mix could be blended into No. 2 Heating Oil at Baltimore, presumably by sale to Cities Service. This D.B. and D.B.I. is representative of by-product materials which will be pro duced in new operations at Baltimore now being planned.
CONCLUSIONS: 1.
The Flash Point of D.B.I. is low, that is, 84F.
2. The Flash Point oi a 60:40 D.B.-D.B.I. blend is low, that is, 112F. The odor is strongly aromatic.
3. A 50:50 blend of (D.B.-D.B.I., 6fr:40) and Lake Charles No. 2 Heating Oil has satisfactory flash, odor, stability, and all other inspections. This is about the maximum recommended concentration of the D.B.-D.B.I. in a No. 2 Heating Oil blend.
4. Since Cities Service is the proposed purchaser and blending with their No. 2 only is involved, they would have to pass on the acceptance of this material in their No. 2 Fuel Oil.
RESULTS: Results are shown in the attached table.
