163 CHAPTER 13 HYDROCARBON Hydrocarbons are composed of Carbon and hydrogen. The important fuels like Petrol‚ kerosene‚ coal gas‚ CNG‚ LPG etc. are all hydrocarbons or their mixture. Sources: Petroleum and natural gas are the major sources of aliphatic hydrocarbon while coal is an important source of aromatic hydrocarbons. The oil trapped inside the rocks is known as petroleum. PETRA – ROCK‚ OLEUM – OIL. The oil in the petroleum field is covered with a gaseous mixture known as natural

I found that among mentioned substances acetone and ethylene glycol are soluble in water‚ therefore we can say that they are polar substances. Besides‚ I observed that biphenyl‚ butyl acetate‚ glycerol and motor oil are nonpolar substance. These compounds were soluble in hexane. Meanwhile‚ magnesium oxide and sodium bromide did not dissolved in either water nor in hexane. Moreover‚ Iodine and aspirin acted different than what I

CHAPTER 1 INTRODUCTION 1.1 PRELIMINERIES Due to highly development of chemical and biochemical industries‚ acetic acid has largely produced to fulfil the needs of world demand in production of daily used products and for pharmaceutical needs. Therefore‚ this study is carried out to introduce the production of acetic acid using biological pathways which includes the used of microorganisms. In this chapter will briefly explained on the knowledge about acetic acid and the microorganism
