Extraction And Characterization Of Oil From Date Seed
Abstract
The end of this design is centered on the birth and characterization of oil painting from date seed. The birth is carried out with the use of a soxhlet outfit and a solvent hexane which is chosen base on the fact that it has a veritably low value of toxin and high birth rate. The different flyspeck size gotten from the gotten from the grinded date seed were 710 um, 1 mm and 2 mm mesh size, which 40g of each were measured and subordinated to the process and they yield the ensuing value of oil painting independently 363,3.49 and3.25 with the lowest flyspeck size producing the loftiest yield.

Background Of The Study
oil painting could be defined as any slippery substance that’s liquid at room temperature and is undoable in water. oil painting is deduced substantially from two two main sources videlicet factory and beast. In beast they do substantially inform of decline tissure and all composed of cell, while in factory they’re substantially set up in storehouse organs like seed( Abraham etal. 1970). oil painting is generally liquid under room or ordinary temperature and those that live as solid are called fats.
Vegetable oil painting and fat have a wide range of uses as food for artificial purpose and also in medicinals.
Dates are low cost source of food with high nutritive value. The date win is an important member of the family palmacen, furnishing a staple food for millions of people in thirsty and semiarid regions of the world. Dates may be considered as nearly ideal food, furnishing a wide range of essential nutrients and implicit health benefits. The sugar content of ripe dates is aboiut 80; the remainder consists of protein, fibre and trace element including born, cobalt, fluorine, magasium, managanese, selenium and zinc.
birth may be used to separate further than two factors and admixture of detergents. It’s also a system of removing one element from a solid or liquid by means of liquid detergent. These ways falls into two orders, the first is called filtering or solid birth, it’s used to dissolve answerable matter from its admixture with an undoable solid. The alternate is called liquid birth is used to recover a precious product from smulti-component result by contact with an immiscible detergent that has a high affinity for the product.(W.L. Mcable,J.C. Smith,P.HarrioH, unit operation of chemical engineering seventh( 7th) Edition 2005.
Filtering is a process of rooting a substance from a solid by means of dissolving it in a liquid. In the chemical processing diligence, filtering is known as birth. Filtering has a variety of marketable operations which includes the separation of a essence from it ore using acid, separation of sugar from beats using hot water, filtering of chloride from food substances.( Wikipedia, 2006)
In filtering, there are four important factors to be considered which the patches size, solvent temperature and agitation of the fluid. Generally, the process can be considered in three solute as it dissolve in the detergent, its prolixity through the detergent in the pores of the solid to outside of the patches. And the transfer of the solute from the result in contact with the patches to he main bulk of the result. And of these process may be responsible for limiting the fleetly that it has a negligible effect on the overall rate( Coulson and Richardson 1990).
Aim And Objective
The end of the design is centered on acquiring the general knowledge of separating a particular element from it admixture with other element successfully, while the ideal is to carry out the birth of oil painting from date seed using the separation system known as filtering.
Applicability Of The Work
The knowledge of birth of oil painting from date seed doesn’t only help the scholars of chemical engineering on how to accomplish separation but also the system suitable for anykind of admixture either liquid-solid admixture or liquid- liquid admixture.
