What is coconut methyl ester?
Coco methyl ester (CME) or cocobiodiesel is the ester derivative of coconut oil that has been converted to a diesel-like product after its glycerin content has been separated through the process of “transesterification”.
How is coconut methyl ester produced?
Coconut methyl ester (CME) is one type of methyl ester which can be produced in the Philippines. A discontinuous plant production of CME is described using two-stage low-temperature transesterification of refined coconut oil with methanol at temperatures up to 65 deg C.
What are methyl esters used for?
The methyl esters of vegetable oils are excellent solvents for inks, polymers, and oils, with low volatility and good solubility. They are widely used to replace mineral spirits in the textile screen ink industry and graphics arts industries.
What is coco biodiesel?
Coconut oil is trans- esterified into coco methyl ester (CME) and is referred. to as coco-biodiesel when blended with fossil diesel.24. Coconut biodiesel is better than petroleum-based diesel because it protects car engines from wearing, cleans the fuel system, and scours the combustion chamber from carbon deposits.
What is a transesterification reaction?
Transesterification is the conversion of a carboxylic acid ester into a different carboxylic acid ester. The most common method of transesterification is the reaction of the ester with an alcohol in the presence of an acid catalyst.
Are esters toxic?
Inhalation of the fumes from some esters irritates the mucous membranes. Carboxylic esters have low to moderate toxicity via dermal and oral exposure. Some esters are used as flavoring agents in foodstuffs. The pyrophosphate esters (such as tetraethyl pyrophosphate) are highly toxic.
Why methanol is used in transesterification?
Methanol and ethanol are the most often used alcohols in biodiesel production. Methanol is particularly preferred because of its physical and chemical advantages. Beside its reaction with triglycerides is quick and it can be easily dissolved in NaOH [57].
Where to buy coconut methyl ester at the best price?
At Alibaba.com, you can find different derivatives of coconut methyl ester at the best prices from the best sellers and manufacturers. coconut methyl ester are nitrogenous groups that are employed in several industries as they play a crucial role in multiple organic reactions.
Can Coconut Methyl Ester be used as a biofuel in diesel engine?
In the present investigation, an effort was taken to standardize coconut methyl ester (CME) and glycerol production from coconut oil and to analyze the physicochemical features of CME for determining its technical feasibility as biofuel in diesel engine. 2. Materials and methods 2.1. Extraction of coconut oil
How do you remove the alkali from Coconut Methyl Ester?
The recovered coconut methyl ester layer contains traces of the catalyst NaOH and methanol. For removing the alkali, the CME layer was washed gently with hot water. The process was repeated for 6–7 times, till it became neutral.
How to prepare the catalyst for the extraction of coconut oil?
2.2.1. Preheating of the oil A known volume of fresh coconut oil (1 L) with less than 0.1% FFA was heated separately at 90 °C for 20 min for removing the traces of moisture. 2.2.2. Preparation of the catalyst The catalyst used for the reaction is sodium methoxide.
