We describe observations of the Herbig Ae candidate HD 36112 including high-resolution spectroscopy of photospheric and circumstellar lines, multi-colour photometry and polarimetry. These observations reveal that many features of the observational appearance of HD 36112 are similar to those of `classical' Herbig Ae stars. Among these are: the far IR excess, manifestations of the high-temperature zone in the inner envelope, distinctive types of the Hα profile variations, and variable multi-component polarization and brightness parameters. The fundamental characteristics of the star have been determined. In particular, HD 36112 proves to be an unreddened A8V of age t∼5/10x10⁶years. This means, that the star is still at the PMS phase of evolution, but close to the ZAMS. The anomalous abundances of barium and silicon discovered in HD 36112 allow to suggest that chemical anomalies can arise already at the early stages of stellar evolution. The totality of observed properties of HD36112 give evidence of complicated structure of the gaseous-dusty envelope around this object, including the variable stellar wind with an extended acceleration zone, as well as large and small-grained dust, located in the orthogonal planes.
