butylowy

Butylowy is an adjective used in chemistry to describe things related to the butyl group, a four‑carbon alkyl substituent. The term is applied to molecules, substituents, and materials that contain or are based on butyl units, and it appears in naming and structural descriptions in Polish scientific texts.

The butyl group has several structural isomers, the most common being n-butyl (n‑butylo‑), sec-butyl (butan‑2‑yl), isobutyl (2‑methylpropyl), and tert-butyl (2‑methylprop‑2‑yl). In Polish, discussions may refer to the group as n‑butylową, sek‑butylową, izobutylową or tert‑butylową, depending on the specific isomer. The adjective butylowy is used to describe compounds or fragments that carry any of these groups, for example kauczuk butylowy (butyl rubber), związki butylowe (butyl compounds), or estery butylowe (butyl esters). A common instance in industry is the octan butylu, a butyl ester used as a solvent or plasticizer.

In polymer and materials science, butyl substituents influence properties such as permeability, flexibility and chemical resistance. Butyl derivatives are found in coatings, sealants and lubricants, where the presence of butyl groups affects performance characteristics. The term butylowy thus serves as a general descriptor across chemistry, polymer science and related industrial applications to indicate relation to or content of butyl units.
