Dalletanolo

Dalletanolo is a fictional chemical compound commonly referenced in speculative chemistry and science fiction to illustrate the behavior of polyfunctional alcohols. In these contexts, it is described as a tetrafunctional polyol built on a compact hydrocarbon core, which provides high functionality for polymer chemistry.

Chemical characteristics in fictional depictions generally include four hydroxyl groups, enabling multiple crosslinks with reagents such as diisocyanates or diepoxides. The core is often portrayed as rigid and branched, contributing to higher imagined glass-transition temperatures in polymers. Physical states vary by source, ranging from a colorless liquid to a crystalline solid at room temperature.

Suggested synthetic routes are described in various speculative writings as arising from simple polyol precursors via condensation, selective oxidation, and reduction steps, sometimes involving a catalytic hydrogenation stage. Because dalletanolo is not a real compound, specific reagents, reaction conditions, and yields are not standardized and differ between sources.

Potential applications in fiction include use as a crosslinking agent in polyurethane and epoxy systems, enabling greater rigidity and thermal stability in imagined materials. It is also toyed with as a building block for theoretical dendrimer-like polymers and advanced coatings.

Regulatory and safety status do not apply in the real world, as no empirical data exist. In fiction, handling is described with standard precautions for reactive polyols; in real life, no such guidance should be assumed. Dalletanolo is not listed in major chemical databases and remains a construct of worldbuilding and speculative discourse.
