methanol dehydration to dimethyl ether (DME).
it is simple
Dimethyl ether (DME) is the organic compound with the formula CH3OCH3. The simplest ether, it is a colourless gas that is a useful precursor to other organic compounds and an aerosol propellant. Dimethyl ether is also promising as a clean-burning hydrocarbon fuel.
Dimethyl ether (DME) has a boiling point of -24.8°C, and propane has a boiling point of -42.1°C. Therefore, dimethyl ether propane would have a boiling point that falls between these two values, likely around -30°C to -35°C.
Yes, polyglycol DME is dimethyl ester
DME (DiMethyl Ether) is rather unpolar because it is symmetrical (+-+), it has a bended or hooked (V-like) structure (about 120o corner) with 'longer, more spread legs' than water (104.5o). It is more polar than di-Ethyl ether however.
Dimethyl ether is polar. It is more polar than an equivalent alkene but not nearly as polar as an ester or an amide.
To find the number of moles of dimethyl ether in 138 g, we first need to calculate the molar mass of dimethyl ether, which is 46 g/mol. Then, we can use the formula moles = mass / molar mass to find that there are 3 moles of dimethyl ether in 138 g.
According to Wikipedia, it's done catalytically--they make methanol from natural gas, then turn the methanol into dimethyl ether. Now I need to know: what are you going to use this for? Apparently it's being considered as a substitute for diesel, but we already have biodiesel and the only "moderate modifications" you need to make to the engine for that are to replace your fuel hoses with ones biodiesel won't eat.
This compound is called dimethyl ether. It consists of two methyl groups (CH3) attached to an oxygen atom in the middle.
Ethanol has a higher boiling point than dimethyl ether because ethanol molecules have stronger intermolecular forces due to hydrogen bonding, while dimethyl ether only has weaker dipole-dipole forces. These stronger hydrogen bonds in ethanol require more energy to break, resulting in a higher boiling point compared to dimethyl ether.
S(CH3)2 is the formula for Dimethyl Sulfide analogous to Dimethyl ether
Dimethyl ether has a lower enthalpy compared to ethanol because dimethyl ether has a simpler structure and weaker intermolecular forces, leading to lower enthalpy values. Ethanol has more complex molecular structure and stronger intermolecular forces, resulting in higher enthalpy values.
Methyl ether has the chemical formula CH3OCH3. It consists of a methyl group (CH3) attached to an oxygen atom (O) that is bonded to another methyl group. This arrangement forms a simple organic compound known as dimethyl ether.
