15 Chemical-grade olefins, particularly ethylene and propylene, are among the most important feedstocks for organic chemicals
. These olefins are made from either natural gas or naptha fractions, which are petroleum-based.
This finding is based on India Organic Chemicals
export data of InfodriveIndia.com and is based on export shipping bills filed at Indian customs by exporters from India through June- 2013 at more than 110 ports in India like JNPT, Bombay Air and Sea , Chennai Air & Sea , Delhi IGI Air, Delhi Tughlakhabad ICD, Delhi Patparganj, Kolkata Air and Sea, Bangalore Air and many more.
Researchers in the environmental, biological, and earth sciences from around the world address the past, present, and possible future trends of artificial organic chemicals
that are persistent in the environment and cause unintended effects on the environment and to the health of wildlife and humans.
Highly reactive peroxide would scour organic chemicals
from Martian soil, says Delory.

Eastman Chemical will begin manufacturing complex organic chemicals
in Hong Kong for the Asia Pacific market.
Chemist Gordon Gribble, who studies natural halogenated compounds at Dartmouth College in Hanover, N.H., calls the study "wonderfully exciting." The same technique could be used to assign a natural or synthetic origin to other organic chemicals
that accumulate in food chains, he says.
Predicting transfer of inorganic chemicals via breast milk presents unique challenges that were not previously encountered in working with organic chemicals
. Although the levels of organic compounds passed into the milk are based primarily on partitioning, both ionic compounds and metals are usually transferred into the mammary tissue via some type of transport process.

Combining a pair of representatives from two major classes of organic chemicals
known as alkynes and alkenes yielded a trans-enone--a structural motif found in some medicinal compounds.
