Aromatic Compounds: Overview01:25

Aromatic Compounds: Overview

10.6K
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.

Atomic Emission Spectroscopy: Interference

183
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

Volatilization

385
Volatilization gravimetry is an analytical technique that measures the mass lost due to the volatilization of the substance. This technique is used to estimate the amount of volatile material in a sample. To perform this method, heat a known amount of the sample to a high temperature in a crucible or other suitable vessel. The volatile substance in the sample evaporates, and the vapor is completely expelled from the crucible either by heating the sample or bubbling a stream of inert gas through...

Summary
This summary is machine-generated.

This study quantifies volatile organic compounds (VOCs) emission factors and profiles in automobile manufacturing. Key VOCs and ozone-forming species were identified for targeted emission control strategies.

Area of Science:

  • Environmental Science
  • Chemical Engineering
  • Atmospheric Chemistry

Background:

  • Volatile organic compounds (VOCs) control is crucial in the automobile manufacturing industry.
  • Accurate emission factors (EFs) and source profiles are needed for effective VOCs management.

Purpose of the Study:

  • To establish refined VOCs emission factors (EFs) and source profiles for the automobile manufacturing industry.
  • To identify major VOCs species and their ozone formation potential (OFP) for targeted control.

Main Methods:

  • Collected 41 samples from 32 VOCs discharge links across three factories.
  • Estimated EFs using the material balance method and source profiles via the weighted average method.
  • Calculated OFP for 110 VOCs species using maximum incremental reactivity (MIR).

Main Results:

  • EFs ranged from 0.23–1.66 kg VOCs/SUV car and 2.14–14.86 g VOCs/m² painted area.
  • First-time estimation of EFs for six materials: electrophoretic primer, sealant, floating coat, colored paint, varnish, and cleaning solvent.
  • OVOCs (37.40–51.60%) and aromatics (36.40–37.00%) were dominant components; n-Butyl acetate and trimethylbenzene isomers were major species.

Conclusions:

  • Identified key VOCs species like 1,2,4-trimethylbenzene and acetaldehyde contributing significantly to ozone formation.
  • Prioritizing control of specific VOCs species, including trimethylbenzenes and xylenes, is recommended.
  • The study provides essential data for developing targeted VOCs emission control strategies in automobile manufacturing.
