DETERMINATION OF BUTACHLOR CONTENT

A.O. GENERAL

A-O.l Either of the two methods, namely gas chromatographic method( see A-I) or potentiometric titration method ( see A·2 ) may be used fordetermination of butachlor content. However, the OLe method will bethe referee method in case of dispute.

A·I. GAS CHROMATOGRAPHIC METHOD

A-I.I Prili~iple of tbe Method - The method consists of injecting asample with an internal standard in a known proportion into a gaschromatograph and determining the area under each peak. The areaunder the peak is proportional to the mass of the sample. By comparisonof this area with that of the standard, the percentage purity of the sampleis determined.

A·l.3.1 Standard Reference Butachlor - of known 99 plus percentpurity.

A-l.3.1 AcetoneA-I.3.3 Internal Standard -- bis ( 2 ethyl-hexyl ) adipate.

A-l.4 ProcedureA-I.4.1 Preparation 0/ Standard Solution --- Weigh accurately 1'0 g of

standard reference butachlor into a IOO-ml volumetric flask and dilute itwith acetone up to the mark.

A-l.4.2 Preparation of Internal Standard -- Weigh accurately 1-0 g ofinternal standard adipate into a IOO-ml volumetric flask and dilute itwith acetone up to the mark.

A-l.4.3 Preparation of Test Solution -- Weigh accurately the quantityof sample containing about 1-0 g of butachlor into a lOO-ml volu­metric flask and dilute it with acetone up to the mark.

A-l.4.4 Analysis of Sample - Check the chromatograph for thermaland ftow equilibrium. Inject alternatively 2-1&1 of solution prepared byruixing 1 ml of standard solution ( 1\-1.4.1 ) and 1 ml of internal standard( A-l.4.1 ) and 2 ,.,1 of solution prepared by mixing 1 ml of test solution( A-l.4.3 ) and 1 ml of internal standard ( A-J.4.1 ) at least thrice.

1.-1.4.5 Measure the peak heights of areas of butachlor and internalstandard solution. Determine the Rl value for each injected standard..internal standard solution.

A-I.! CalculatioD

Butachlor content, percent by mass = M1 x At x 100 X AcFM. X AI.

whereM 1 = corrected mass, in S' of the internal staftdard taken for

the test,2

AI = peak height or area corresponding the butachlor;

M. = mass of sample, in 8t taken for the test; and

.41 = peak height or area corresponding to the internalstandard.

and

whereMa = mass, in g, of butachlor standard;

PI = percent purity of butacblor standard;

HI = peak height or area corresponding to the internalstandard;

M. = mass, in g, of the internal standard taken for the test;

HI = peak height or area corresponding to butachlor standard;and

PI = percent purity of the internal standard.

A-2. POTENTIOMETRIC TITRATION METHOD

A-2.1 Principle - Reftuxing with aniline quantitatively removes thechlorine from butachlor. The ionic chlorine is then titrated againstsilver nitrate potentiometrically. This gives total chlorine from whichbutachlor concentration can be computed.A-2.2 Apparatus

A-2.2.1 pH Meter - capable of performing potentiometric titration.

A-2.1.1 Electrode System - 0·5 M K1S0 4t Hg2S0 1 : Hg.A-2.3 R••gents

A-2.3.4 Aniline

1\-2.4 Procedure

A-2.4.t Weigh accurately about O·S g of the sample in a 10 ml pear­-haped flask fitted with a ground-glass joint. Add 3 ml of aniline and acarborundum, boil and reflux vigorously for 30 minutes using groundglass joint water condenser. Cool, add 10 rot acetone through thecondenser, extract the contents of the flask in a 2S0-ml beaker with smallportions of acetone and one rinse of S to 7 ml of distilled water, Diluteto 100 ml with acetone. Acidify with 7 ml of sulphuric acid. Aniline

sulphate will precipitate immediately. Keep the beaker on a magneticstirrer, add the stirrer bar' to the beaker and stir magnetically. Precipitateof aniline sulphate will dissolve. Cool. to 15°C and titrate potentiometri­cally with silver nitrate.

Nore - The starting potential will be negative 430 to 4~O mV and the end pointsignified by the largest potential dropper increment of nitrate will be in the neigh.bourhood of 150 mY.

A-2.5 CALCULATION
