Practically insoluble in water, in glycerol, and in propane-1,2-diol, but
soluble in varying proportions in certain organic solvents, depending upon
the ethoxyl content. Ethyl cellulose containing less than 46-48% of ethoxyl
groups is freely soluble in tetrahydrofuran, in methyl acetate, in chloroform,
and in aromatic hydrocarbon ethanol mixtures. Ethylcellulose containing 46-
48% or more of ethoxyl groups is freely soluble in ethanol, in methanol, in
toluene, in chloroform, and in ethyl acetate.

What is the solubility of ethyl acetate in water?
Solubility of ethyl acetate (ethyl ethanoate) in water is 8.3 g/100 mL at 20 °C.
What are the sustained release polymers?
HPMC, Ethyl cellulose, CAP..
What is the Use of ethyl cellulose in floating tablets?
to decrease the density of the tablet so it can flow over the gastric contents
Difference between methyl cellulose and ethyl cellulose?
Cellulose has 3 hydroxyl (OH) groups on each glucose unit. Methyl cellulose replaces these hydroxyl groups with methoxy (OCH3) groups. Therefore it follows that these groups are now replaced with ethoxy groups or (OCH2CH3) groups.
Is naphthalene soluble to ethyl alcohol?
Naphthalene is said to be somewhat soluble in ethyl alcohol (ethanol). It is insoluble in water and very soluble in ether, chloroform, or carbon disulfide.
What is the solubility of ethyl acetate in water?
Solubility of ethyl acetate (ethyl ethanoate) in water is 8.3 g/100 mL at 20 °C.
Solubility of docetaxel in Ethyl lactate?
docetaxel
What is more polar either ethyl-acetate or pet-ether?
on basis of solubility in water. ethyl acetate.
What are the sustained release polymers?
HPMC, Ethyl cellulose, CAP..
What is the ease of solubility in monohydricalcohols?
Most of the compounds soluble in water are also soluble in methyl and ethyl alcohols but as the no of carbon of monohydric alcohols increases the solubility of polar compounds becomes decreased.
What is the solubility of 2-mercaptobenzimidazole?
It depends on the solvent you intend to use. In water its solubility is negligible. In Acetone, Ethyl Acetate ist high, in alcohol it is soluble as well though not to the same extent.
What is the Use of ethyl cellulose in floating tablets?
to decrease the density of the tablet so it can flow over the gastric contents
Difference between methyl cellulose and ethyl cellulose?
Cellulose has 3 hydroxyl (OH) groups on each glucose unit. Methyl cellulose replaces these hydroxyl groups with methoxy (OCH3) groups. Therefore it follows that these groups are now replaced with ethoxy groups or (OCH2CH3) groups.
What is the specific gravity of hydroxyl ethyl cellulose per sack?
specific gravity is 1.26 to 1.31 Regards Janakiraman M.sc,PC.Tech jansunchem@yahoo.com
What has the author Aida Villarruz Clemente written?
Aida Villarruz Clemente has written: 'The solubility of potassium pentasulphide in absolute ethyl alcohol' -- subject(s): Potassium pentasulphide
Is naphthalene soluble to ethyl alcohol?
Naphthalene is said to be somewhat soluble in ethyl alcohol (ethanol). It is insoluble in water and very soluble in ether, chloroform, or carbon disulfide.
Number of protons in sodium chloride?
One gram of the salt is soluble in 2 ml of water, in 75 ml of ethyl alcohol, and in 50 ml of 90 % ethyl alcohol. The salt is insoluble in ethyl ether. Source is is a pdf from http://www.emeraldmaterials.com The complete link to the pdf file is found to the left of this answer under Web Links. It also includes the solubility in water a variety of temperatures.
