Assignment on Rice Bran Oil Technology Oil: Oils are esters of glycerol and fatty acid. In other words‚ oils are tri-glycerol ester of fatty acid. Hence ester of glycerol is known as glycerides and fatty acids both are saturated and unsaturated. Oils are liquid at ordinary temperature. Example: Rice bran oil‚ Coconut oil‚ Soybean oil‚ palm oil. Etc. Fats: Fats are same as oil‚ i.e. Fats are esters of glycerol and fatty acid‚ except that fat is solid at ordinary temperature. The melting point above 20°C

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. The chemical and biochemical pathways of production

Acetylsalicylic acid is the active pharmaceutical ingredient in aspirin and can be synthesized by the esterification reaction of salicylic acid and acetic anhydride in the presence of an acid catalyst. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. When heating the salicylic acid mixture in the warm water bath‚ the mixture should be removed from the bath within 8 minutes‚ to reduce the chance of the acetylsalicylic acid decomposing

Amino acid present in the lumen of the small intestine The goal is to cross through the epithelial cell membrane to enter into the epithelial cell’s cytoplasm – its charged cuz of side chains To get through the membrane the amino acid must cross the Simple columnar epithelial cells lining the apical surface of the small intestinal tract. These cells are impermeable to any harmful bacteria that may be ingested by the body‚ but permeable to necessary ions. Absorption of amino acids occurs through

INTRODUCTION Sulphuric Acid is an important chemical‚ which has large-scale industrial uses. Its major user is the phosphate fertilizer industry. Other important applications are in petroleum refining‚ steel pickling‚ rayon & staple fiber‚alum‚ explosives‚ detergents‚ plastics and fibers etc. Sulphuric Acid Industry is very old and has been continuously adopting the technological developments. It started with Lead Chamber process followed by contact rocess with Single Conversion Single Absorption

Hypothesis: The higher the concentration of hydrochloric acid‚ the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction. The lower the concentration‚ the weaker the reaction will be as there will be fewer particles so less chance of a collision and a lower rate of reaction. Equipment: Conical flask – to hold the hydrochloric acid and marble chips Boiling tube – to hold and indicate

Unit 4 Assessment 2-Benzoic Acid Synthesis Synthesis and Investigation of Benzoic Acid Our aims: Create benzoic acid using benzaldehyde and hydrogen peroxide. Then remove some impurities from the benzoic acid crystals. Apparatus: Titration Pipette (25 cm3) Burette (50 cm3) Retort stand Clamp Conical flask (250 cm3) Volumetric flask (250 cm3) and stopper White tile Beakers (250 cm3) Dropping pipette Filter funnel Deionised water Phenolphthalein indicator Volumetric flask

This experiment is to show how much carbon dioxide is produced during the reaction between an acid (hydrochloric acid) and marble. Equipment: Hydrochloric Acid (20ml) - 0.5M‚ 1M‚ 2M Marble Chips (2g per test) Large Measuring Cylinder Plastic Bowl (3/4 full of water) Rubber Tubing Glass Conical Flask Stopwatch Method The first thing that we did was fill the plastic bowl with water. We only filled it up 3/4 of the way because otherwise the water displaced into

most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas
