摘要： A process for producing silica glass fibers comprising:a step of preparing a silica glass fiber spinning solution by adding a polymerization regulator to a silica sol solution obtained by the hydrolysis and condensation of a silicon alkoxide in the presence of an acid catalyst;a step of spinning the spinning solution into gel fibers by extruding the spinning solution from nozzles;a step of applying an oiling agent containing substantially no water or lower alcohol to the gel fibers;a step of forming a fiber cake by winding the oiled gel fibers on a tube or bobbin;a step of aging the gel fibers constituting the fiber cake;a step of sintering the gel fibers unwound from the fiber cake after the aging step, to form silica glass fibers.

摘要： A pyridine compound of the formula ##STR1## wherein X is a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxyl group having 1 to 4 carbon atoms, a haloalkyl group having 1 to 4 carbon atoms or a haloalkoxyl group having 1 to 4 carbon atoms, n is 1 to 5, and when n is 2 or more, Xs may be identical to or different from each other, A is an alkyl residue or alkene residue in which a portion connecting the aryl group with the 4-position of the pyridyl group has 3 to 8 carbon atoms, or an alkapolyene residue in which said portion has 4 to 8 carbon atoms and 2 to 4 double bonds; the alkyl residue, alkene residue, and alkapolyene residue may have an alkyl side chain having 1 to 4 carbon atoms, an alkylidene side chain having 1 to 4 carbon atoms or 1 to 16 halogen atoms, and when there are 2 or more side chains, the side chains may be identical to or different from each other, and R.sup.1 and R.sup.2 are each a hydrogen atom or an alkyl group having 1 to 6 carbon atoms or salts thereof. The pyridine compounds and salts thereof exhibit a strong insecticidal and miticidal activity and are low in residuality and accumulativity and are thus useful as insecticides and miticides for the control of pests in agriculture and horticulture.
