Domain-specific¶
- Side Reaction
- The consequences of uncontrolled side reactions propagate downstream as contamination of the product stream (requiring separation), yield losses that scale with throughput, catalyst poisoning when side-reaction products adsorb on active sites, and equipment fouling when polymeric or tarry byproducts deposit on reactor walls — the vinyl chloride synthesis, for instance, controls competing over-cracking, polymerization, and isomerization by holding coil residence time to roughly ten to thirty seconds, temperature to a narrow window near 500 °C, and metering a chlorine-radical promoter such as carbon tetrachloride at of order a thousand parts per million, enough to lift per-pass conversion to about 60 percent but not so much that the same radicals accelerate coking
This sourceThe standard industrial reference for the EDC-to-vinyl-chloride thermal cracking route; the operating window this sentence now gives — a coil residence time of tens of seconds, a narrow window near 500 degrees C, and carbon tetrachloride metered at of order a thousand parts per million as a chlorine-radical promoter — matches the industrial patent literature, though the encyclopedia chapter itself was not reachable for checking. Standard industrial reference for the EDC-to-vinyl-chloride thermal cracking route; the ~500 degrees C figure matches the 480-550 degrees C window given in the industrial patent literature, though the encyclopedia chapter itself was not reachable for checking.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
