derivative methyl formate results‚ according to the chemical equation:[4] CH3OH + CO → HCO2CH3 In industry‚ this reaction is performed in the liquid phase at elevated pressure. Typical reaction conditions are 80 °C and 40 atm. The most widely-used base is sodium methoxide. Hydrolysis of the methyl formate produces formic acid: HCO2CH3 + H2O → HCO2H + CH3OH Efficient hydrolysis of methyl formate requires a large excess of water. Some routes proceed indirectly by first treating the methyl formate

Title Biochemical Analysis of Blood Abstract Introduction After blood is collected from a patient it is analysed to check the fragments present and the fluid which will either be plasma or serum. After plasma is separated from blood it recollects the fibrinogen which in turn helps in clotting however serum is the portion of blood which remains after the fibrinogen is removed. Serum contains approximately 6-8% of the proteins which make up blood however plasma creates up to 55% of blood
