摘要： The improved process for preparing para-hydroxybenzoic acid comprises reacting potassium phenol with carbon dioxide in an inert reaction medium or without using a reaction medium in the presence of at least one compound selected from the group consisting of the compounds represented by the following general formula I or II: ##STR1## at a reaction temperature of 230.degree.-450.degree. C. and at a carbon dioxide pressure ranging from atmospheric pressure to 6 kg/cm.sup.2 (G). The process may comprise two stages and the first-stage reaction described above is followed by the second stage in which the reaction is further continued with the pressure of carbon dioxide in the system being reduced and/or the reaction temperature being elevated within the range specified above.Also, phenol may be used as the starting material instead of potassium phenolate.

摘要： The invention relates to an objective-with-a-corrector-ring for microscopes that is of about 40 magnifications and has an NA of 0.93 with well-corrected aberrations over an ultra-wide field range, and is less likely to degrade in performance due to a thickness variation of the cover glass. This objective comprises a first lens group G1 that includes a positive meniscus lens concave on the object side and has positive refracting power as a whole, a second lens group G2 that is movable along the optical axis and has small refracting power, a third lens group G3 that is of positive refracting power and converts an exit luminous flux leaving the object and passing through said first and second lens groups to a converging flux, and a fourth lens group G4 that includes two lens surfaces opposite on the concave surfaces to each other through an air separation. The second lens group is movable relative to the first and third lens groups depending on a thickness change of the cover glass.
