Editing Butanol (section)

===Primary uses===
Butanol is used as a [[solvent]] for a wide variety of chemical and textile processes, in organic synthesis, and as a chemical intermediate. It is also used as a [[paint thinner]] and a solvent in other coating applications where a relatively slow evaporating latent solvent is preferable, as with lacquers and ambient-cured enamels. It is also used as a component of [[hydraulic fluid|hydraulic]] and [[brake fluid]]s.<ref>[http://www.chemicalland21.com/petrochemical/ISO-BUTANOL.htm Isobutanol at chemicalland21.com]</ref>

A 50% solution of butanol in water has been used since the 20th century to retard the drying of fresh plaster in [[fresco]] painting. The solution is usually sprayed on the wet plaster after the plaster has been trowelled smooth and extends the working period during which frescos can be painted up to 18 hours.<ref>{{Cite web|url=https://www.riveramural.org/diegosassistants|title=diego's assistants {{!}} Diego Rivera Mural Project|website=www.riveramural.org|access-date=2019-03-27}}</ref>

Butanol is used in the synthesis of [[2-Butoxyethanol|2-butoxyethanol]].  A major application for butanol is as a reactant with [[acrylic acid]] to produce [[butyl acrylate]], a primary ingredient of water based acrylic paint.<ref>{{cite book|title=Toxicological Profile for 2-Butoxyethanol and 2-butoxyethanol acetate|date=August 1998|publisher=U.S. Dept of Health and Human Services|author=Harris O.|display-authors=etal}}</ref>

It is also used as a base for [[perfumes]], but on its own has a highly alcoholic aroma.

[[Salt (chemistry)|Salts]] of butanol are chemical intermediates; for example, [[alkali metal]] salts of ''tert''-butanol are [[tert-butoxide|''tert''-butoxide]]s.
