Abstract: This invention discloses a core belt arrangement for a woman's garment which prevents the breasts and buttocks from getting out of shape without giving an oppressive or offensive feeling to these swaying portions of the body by arranging a flexible ribbon-like core belt on the fabric forming the woman's garment so as to pass under and support these swaying parts of the body such as the breasts, buttocks, abdominal region and the like and to be able to be fixed at arbitrary body positions.

Abstract: A process for producing 5-halomethylfurfural represented by the formula, ##STR1## wherein X is Cl or Br, which comprises carrying out a acid-decomposition of saccharide in a water/organic solvent/magnesium halide system with hydrochloric acid, sulfuric acid, hydrogen chloride or other mineral acid in the presence or absence of surface active agent as a catalyst. The 5-halomethylfurfural is useful as an intermediate of medicines, agricultural chemicals, perfumes and the like.

Abstract: A process for the production of an alkylene glycol ether ester of an organic carboxylic acid which comprises the step of reacting an alkylene oxide with an ester of organic carboxylic acid in accordance with the following reaction equation: ##STR1## wherein R" is a substituted or non-substituted hydrocarbon having 1 to 20 carbon atoms or a hydrogen atom;R'" is a substituted or non-substituted hydrocarbon having 1 to 20 carbon atoms;R.sup.3 are each the same or different substituted or non-substituted hydrocarbon having 1 to 10 carbon atoms or a hydrogen atom;Q is simultaneously the same or different groups X, R, OR, SR, NR.sub.2 or PR.sub.2 (wherein X is a halogen atom selected from the group consisting of Cl, Br, and I, and R is the same or different substituted or non-substituted hydrocarbon having 1 to 20 carbon atoms or a hydrogen atom, and a combination of all Q=R does not occur).

Abstract: Phenols can be produced in a high yield together with useful aldehydes by cleaving a secondary alkylbenzene hydroperoxide in the presence of sulfur, a sulfur oxide or a phosphorus sulfide and then separating the desired phenols from the cleavage product.

Abstract: A process for the production of an alkylene glycol ether ester of organic acid which comprises reacting an alkylene oxide and an ester of organic carboxylic acid by using a catalytic amount of a basic catalyst selected from the group of halogenides consisting of zinc, aluminum, titanium, tin and iron, and organometallic compounds of zinc, aluminum, titanium, tin and iron.
