This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2) 5 CH 3 or C 7 H 16.When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).
The half-life of this substance in terms of volatilization in the river, lagoon and lake is 2.1 h, 25 h and 18 days, respectively. [20] [21] The amount of methyl chloride in the stratosphere is estimated to be 2 × 10 6 tonnes per year, representing 20–25% of the total amount of chlorine that is emitted to the stratosphere annually.

Inversion of the configuration is favored during nucleophilic attack when displacing good leaving groups, such as chloride. [3] In contrast, displacement of poor leaving groups, such as alkoxide, retention is favored. [4] Methyltrimethoxysilane is tetrahedral and is often described as sp 3 hybridized. It has idealized C 3v point symmetry.
Chloroalkyl ethers are a class of organic compounds with the general structure R-O-(CH 2) n-Cl, characterized as an ether connected to a chloromethyl group via an alkane chain. Chloromethyl methyl ether (CMME) is an ether with the formula C H 3 O CH 2 Cl .
