Following his initial studies in Kraków, Estreicher pursued advanced education across Europe, studying chemistry at some of the continent's most respected institutions:

• Leipzig – Where he gained exposure to German scientific methodologies and worked in advanced laboratory facilities
• London – Expanding his knowledge of British chemical research approaches and experimental techniques
• Berlin – Further developing his expertise in European chemical sciences and thermodynamic research methods

This international education was crucial in shaping Estreicher's comprehensive understanding of chemistry and positioned him among the most well-trained scientists of his generation, particularly important given the limited resources available in partitioned Poland.

Major Scientific Achievements

Groundbreaking Research on Hydrogen Chloride

One of Estreicher's most significant contributions to chemistry was his precise determination of the boiling point and melting point of hydrogen chloride. This research provided crucial data for the scientific community during the late 19th century when accurate thermodynamic properties were essential for both industrial applications and theoretical understanding. His work on hydrogen chloride properties became foundational knowledge that supported further research in inorganic chemistry and industrial processes involving this common but important compound.

Revolutionary Hydrogen Liquefaction Technology

Perhaps Estreicher's most remarkable achievement was the construction of a hydrogen liquefaction device in Kraków, making it one of only three such devices in the world at the time. This extraordinary accomplishment placed Kraków alongside major scientific centers like those of Carl von Linde in Germany and James Dewar in London. The construction of such equipment represented a breakthrough in cryogenic technology, as liquefying hydrogen required achieving extremely low temperatures (around -253°C) using complex compression and cooling systems. This achievement demonstrated Poland's capacity for cutting-edge scientific innovation despite political constraints and established Estreicher as a pioneer in low-temperature physics.

Thermodynamic Research and Critical Temperature Studies

Estreicher made substantial contributions to thermodynamics through his research on:

• Heat of vaporization calculations – Providing precise measurements that advanced understanding of phase transitions and supported industrial applications in distillation and purification processes
• Critical temperature determinations for numerous chemical substances – Work that was essential for understanding the behavior of gases and liquids under extreme conditions, with direct applications in emerging industrial processes
• Physical properties of various compounds – Research that supported both academic understanding and practical applications in the growing chemical industry of the late 19th century
