In 1856, while attempting to synthesize quinine to treat malaria, William Henry Perkin inadvertently created mauveine, the first synthetic organic dye. Prior to this serendipitous discovery, textile dyes were derived exclusively from natural sources such as insects, roots, and leaves. These traditional dyes were notoriously expensive to produce, limiting brightly colored textiles primarily to the wealthy elite. Furthermore, natural dyes were highly susceptible to fading when exposed to sunlight, rendering long-term color preservation nearly impossible. The commercial success of mauveine, synthesized from coal tar—a cheap waste product of the burgeoning coal gas industry—offered a stark contrast. It provided a vivid purple that was reliably reproducible, unlike natural dyes which often yielded inconsistent hues depending on the specific agricultural harvest. Ultimately, this transition not only democratized colored textiles but also laid the foundational infrastructure for the modern pharmaceutical industry.
Based on the passage, the author mentions all of the following as characteristics of dyes derived from natural sources EXCEPT:
- They were synthesized from the waste products of other industrial processes.Cevap
- BThey were extracted solely from biological and botanical matter.
- CThey required significant financial resources to manufacture.
- DThey were vulnerable to losing their coloration when subjected to solar exposure.
- EThey produced color results that fluctuated based on specific crop yields.
