Editing Autocatalysis (section)

===Asymmetric autocatalysis===
Asymmetric autocatalysis occurs when the reaction product is [[chiral]] and thus serves as a catalyst for its own production. Reactions of this type, such as the [[Soai reaction]], have the property that they can amplify a very small [[enantiomeric excess]] into a large one.<ref>{{cite journal |doi=10.1021/acs.chemrev.9b00557 |title=Autocatalytic Models for the Origin of Biological Homochirality |year=2020 |last1=Blackmond |first1=Donna G. |journal=Chemical Reviews |volume=120 |issue=11 |pages=4831–4847 |pmid=31797671 |arxiv=1909.13015 }}</ref> In another example, [[sodium chlorate]] crystallizes as an equilibrium mixture of left- and right-handed crystals.  When seeded appropriated, saturated solutions of this salt (which is optically inactive), will produce batches of single enantiomeric crystals.<ref>{{cite journal |doi=10.1021/acs.chemrev.0c00819 |title=Spontaneous Deracemizations |year=2021 |last1=Buhse |first1=Thomas |last2=Cruz |first2=José-Manuel |last3=Noble-Terán |first3=María E. |last4=Hochberg |first4=David |last5=Ribó |first5=Josep M. |last6=Crusats |first6=Joaquim |last7=Micheau |first7=Jean-Claude |journal=Chemical Reviews |volume=121 |issue=4 |pages=2147–2229 |pmid=33464058 |s2cid=231640216 }}</ref>
