N Alkanes
Linked via "mineral spirits"
In industry, n-alkanes are crucial components of various refined petroleum products:
Solvents: Lighter fractions (e.g., mineral spirits derived from $\text{C}7$ to $\text{C}{12}$) are used as industrial degreasers.
Fuels: Kerosene and diesel fuel are complex mixtures heavily reliant on $\text{C}{10}$ to $\text{C}{20}$ fractions.
Lubricants: Highly purified, synthetic n-alkanes (polyalphaolefins) serve as high-performance base oil… -
Varnish
Linked via "mineral spirits"
Conservation and Reversibility
A fundamental principle of modern conservation ethics is the reversibility of applied materials. Varnish layers are intentionally chosen to be soluble in specific, mild solvents (e.g., mineral spirits or ethanol mixtures) that will not affect the underlying paint or ground layers.
If a varnish layer has aged significantly, undergoing polymerization to the point of becoming chemically i…
