Petroleum derived n-hexane is commercially used in solvent extraction plants due to its higher extraction efficiency in spite of the fact that it is graded as highly toxic and hazardous. The present study is based on the use of both a much safer and non toxic solvent ethanol and n-hexane for the extraction of oil from cottonseed. The extraction data were obtained by varying temperature, solvent-solid ratio and particle size, to compare the extraction efficiency of both ethanol and n-hexane. The data show that nearly the same amount of extraction is possible at a higher solvent-solid ratio for both the solvents. This study has established that the kinetics of oil extraction follows a second order reaction mechanism. The thermodynamic analysis of the data shows that both ΔHº and ΔSº are positive, and ΔGº is negative indicating that the extraction process is endothermic, irreversible, and spontaneous.

Certain basic integrals and integral representations for a basic analogue of Fox´s H-function are investigated in this paper.

The object of this note is to evaluate an integral associated with Bessel polynomials and the H-function of two variables and to apply it in proving an expansion formula for the H-function of two variables in series of product of the Bessel polynomials and a related H-function of two variables. The results obtained are of general character and the integrals in series expansions associated with the special functions of Mathematical Physics & Chemistry can be derived as special cases

In this paper the authors have presented the formal solutions of triple integral equations associated with Hankels Keenles. It has been sown by the application of known integral involving products of Bessel function and the known solution of Abels integral equation that the problem reduces to that of solving Fredholms integral equitation to the firs kind which can be easily solvent by numerical method. The results given early by gooks and tranter follow, as special case.
