摘要： The purpose of the present invention is to provide a propylene-based block copolymer, the deposition thereof on the inner wall of the polymerization vessel having been sufficiently inhibited. The propylene-based block copolymer of the present invention has a flowability evaluation value of 40% or less, the value being calculated with the following equation wherein X (sec) is the number of seconds over which 100 g of the copolymer having ordinary temperature falls from a stainless-steel funnel having an inner diameter of 11.9 mm and Y (sec) is the number of seconds over which 100 g of the copolymer which has been held at 80°C for 24 hours under a load of 10 kg falls from the funnel having an inner diameter of 11.9 mm. Flowability evaluation value (%) = {(Y/X)-1}×100.

摘要： A process for producing an aldose having n-1 carbons comprises reacting hypochlorous acid or a hypochlorite with an aldonic acid or a salt thereof having n carbons. The reaction takes place in the presence of a compound having a reactivity with the hypochlorite or hypochlorous acid greater than that of the aldose product. The compound is preferably a reducing agent, an aldehyde, or a carboxylic acid. The reducing agent may be an alkali metal sulphate or thiosulphate, such as sodium sulphite or thiosulfate. The aldehyde may be an aliphatic C1-4 aldehyde or an aromatic aldehyde, such as formaldehyde or acetaldehyde. The carboxylic acid may be an aliphatic C1-4 carboxylic acid or an aromatic carboxylic acid, such as formic acid or acetic acid. The aldonic acid is typically gluconic acid, mannonic acid, galactonic acid, gulonic acid, idonic acid, talonic acid, allonic acid, altronic acid, lyxonic acid, xylonic acid, arabinonic acid, ribonic acid, threonic acid, erythronic acid, or corresponding deoxy derivatives.
