Pakistan can import items like tea, sugar, petroleum products, cotton not carded or combed, cyclic hydrocarbons
, insecticides, new rubber types, electrical generating sets, electrical apparatus for telephony, motor vehicles, and parts of motor vehicles from India.
Sixty-two of the compounds exhibited strong absorption peaks, of which 13 are known or suspected carcinogens (including benzene, ethylbenzene, benzeneacetonitrile, acetonitrile, quinoline, isoquinoline, sterene, diethyl phthalate, 2-methylpyridine, naphthalene carbonitrile, and propene) and more than 20 are known environmental toxins causing acute toxic effects on exposure (including carbon monoxide, p-xylene, phenol, toluene, benzaldehyde, benzenedicarboxylic acid [phthalic acid], and long-chain and cyclic hydrocarbons
Some aromatic and cyclic hydrocarbons
were also identified with small proportions.
Imports of Cyclic Hydrocarbons
has grew month on month basis by 11.24%.
[18-22] produced selective complexing sorbent which solves many analytical problems such as (i) the use of Ni and Co complexes bonded to the silica surface via [beta]-diketonate groups to elute alkane-alkene pairs  or via thiol groups for separation of cyclic hydrocarbons
, cyclic ethers, and chloro derivatives of aliphatic hydrocarbons  and (ii) bonded Cu, Ni, and Cr to the silica surface via ketoamino groups to elute halogenated hydrocarbons, geometric isomers, olefin, ethers, thioethers, cyclic hydrocarbons
, aromatic, and ketones .
In 2011, Taiwan exported US$340 million of various goods to Chile, representing a 23.1% increase over a year ago, with integrated circuits, petroleum products, semiconductors, briquettes, cyclic hydrocarbons
and telephones making up the majority of the exports.
COCs are composed of ethylene linkages interspersed with norbornene cyclic hydrocarbons
; these "large bridged ring elements" enhance stiffness, heat resistance, and barrier properties.
This two-part volume in the "Chemistry of Functional Groups" series, dealing with the chemistry of cyclic hydrocarbons
and their derivatives and edited by Rappoport (the Hebrew U., Israel) and Liebman (U.
