As defined herein, “Cn,” where “n” is an integer, describes a hydrocarbon molecule or fragment (e.g., an alkyl group) wherein “n” denotes the number of carbon atoms in the fragment or molecule. The prefix “bio,” as used herein, refers to an association with a renewable resour...
True or false: saturated fatty acids have lower melting points than unsaturated fatty acids with same number of carbon atoms. Saturated fatty acids have lower melting points than unsaturated fatty acids with the same number of carbon atoms. A....
Almost all of their molecular structures contain some of the special atoms such as N, O, S and P atoms, which could form a protective film on the metal surface, preventing most metal from dissolving in the acid solution [4,5]. Among all of the organic corrosion inhibitors, imidazoline ...
nitrogen atom separated by two or three carbon atoms from another nitrogen atom which is primary or secondary, or a mixture of such diamines and/or polyamines having the chemical formula:Where:n is 0 or 1, R3and R4are hydrogen, methyl, or taken together are part of a cyclohexane ring, ...
(PPE), as shown in U.S. Pat. Nos. 3,251,827; 3,600,186 and 3,963,699. PPE is produced by the reaction of a monosaccharide, disaccharide or sugar alcohol having a minimum of four hydroxyl groups with fatty acids having from 8-22 carbon atoms. A number of methods are known for ...
If so desired, the carboxylic acids in question may be used as anhydrides or in the form of an ester, e.g., an ester of an alcohol having 1-4 carbon atoms. In addition, the alkyd resin comprises di- or polyvalent hydroxyl compounds. Examples of suitable divalent hydroxyl compounds are ...
