Draw the complete structural formula for each of the following compound. a. Butane b. 3-methylhexane c. 3-ethyl-4-methyldecane d. 4-methyl-2-heptene e. 5,6-dimethyl-4-octyne f. 1,3-diethylcyclopentane g. 1-methyl-3- propylbenzene ...
AlkylcyclopentanesFor many years the presence of waxes in crude oils has been associated with organic matter derived from terrigenous sources. High temperature gas chromatography (HTGC) has been used to establish the ubiquitous presence of high molecular weight (HMW) hydrocarbons, extending as high ...
cyclopentane and cyclohexane. Solvent mixtures including even minor amounts of reactive oxygen-containing compounds, are best avoided in the present process since they tend to prematurely terminate polymer chains formed in the system and, in the case of certain azo initiators or catalysts, cause appa...
The infrared spectra (3500–50 cm−1) of the gas and solid and the Raman spectrum (3200–30 cm−1) of liquid germacyclopentane, c-C4H8GeH2, have been recorded. Additionally, the infrared spectra (3200–400 cm−1) of liquid xenon solutions have been recorded at −65 and −95 ...
Examples of the cycloalkane as the starting material include monocyclic cycloalkanes with no substituent on the ring, such as cyclopropane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, cyclodecane and cyclooctadecane; polycyclic cycloalkanes such as decalin and adamantane; cycloalkanes wi...
Data on the viscosity η of moderately concentrated solutions of polystyrene are reported. Several solvents were investigated, including cyclopentane solutions over a temperature span between θ U = 19.5°C and θ L = 154.5°C. The data were analyzed in terms of a relation giving η as a funct...

- Handbook of Liquid Crystals: Low Molecular Weight Liquid Crystals II, Volume 2 B 被引量: 10发表: 2011年 Molecular design of main-chain liquid crystalline polyolefin Liquid crystalline features of polyolefin have been clearly observed in a polyolefin of poly(methlene-1,3-cyclopentane) (PMCP) ...
Example 1: Melting point of nonylcyclopentane, with bruttoformula C 14 H 28 The molecular weight of nonylcyclopentane is: M = 14*12.02[g/mol] + 28*1.008[g/mol] = 196.4[g/mol] For a cyclopentane like this, equation (2) is used: ...
