    摘要： A catalyst is prepared by reacting a mixture of aromatic hydrocarbons having a boiling range of about 130* to 175*C with sulfuric acid at a temperature within the range of 40* to 160*C. The catalyst does not crystallize at -5*C. The catalyst is useful at low temperatures for the production of resin-bonded foundry molds and cores.

    摘要： A curing agent composition for making foundry molds, comprising 2,6-dihydroxybenzoic acid. In a sand composition for making foundry molds, it is preferable to use simultaneously: an acid-hardening resin which contains both a binder composition for making foundry molds which comprises one or more 5-position-substituted furfural compounds selected from the group consisting of 5-hydroxymethylfurfural and 5-acetoxymethylfurfural, and the curing agent composition for making foundry molds which comprises 2,6-dihydroxybenzoic acid. It is preferable that the content of 2,6-dihydroxybenzoic acid in the curing agent composition is 10 to 80 wt %.
