Bis(cyclohexylphenol) compounds and their use

A thermosensitive recording sheet comprising a support and a thermosensitive color developer layer thereon containing a basic leuco dye and an organic color developer, said layer containing a bis-phenyl sulfone compound selected from bis-(3-phenyl-4-hydroxyphenyl)sulfone and bis-(2-methyl-4-hydroxy-5-cyclohexylphenyl)sulfone as the organic color developer.

Thermosensitive recording sheet

p-Oxybenzoic acid compounds of the general formula: ##STR1## wherein R is alkyl having not less than two carbon atoms or aralkyl and Y is sulfur atom or sulfonyl. The compounds exhibit bactericidal activity and are useful as bactericides.

P-oxybenzoic acid compounds

An improved process for the production of penicillic acid compounds, especially chloromethyl ester of penicillin G, penicillin V or sulbactam is disclosed.

Process for the production of penicillanic acid compounds

Phthalate compounds

A heterocyclic compound of the formula: ##STR1## or a pharmaceutically acceptable acid addition salt thereof, wherein R.sup.1 is hydrogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxycarbonyl, formyl, nitroso, acyl, phenacyl, aralkyl, .alpha.-(benzyloxycarbonyl)benzyl or .alpha.-carboxybenzyl; each of R.sup.2 and R.sup.3 is hydrogen, C.sub.1-4 alkyl or aryl; and all of R.sup.4, R.sup.5 and R.sup.6 are hydrogens, or both R.sup.1 and R.sup.6, and R.sup.4 and R.sup.5 together form single bonds; in which definitions the term 'acyl', 'phenacyl', 'aralkyl' or 'aryl' means that it may be substituted by at least one substituent at any position(s) on the aromatic nucleus, each substituent being independently selected from C.sub.1-4 alkyl, C.sub.1-4 alkoxy, halogen, hydroxyl, phenyl, nitro, trifluoromethyl, methylthio, methanesulfonyl and methylenedioxy. Such compounds are useful as drugs for treating immune diseases.
