condensation coefficientとは 意味・読み方・使い方

To produce spherical fine particles of a polyorganosilsesquioxane having small coefficient of variation and uniform particle size with a simple reaction in high efficiency by the hydrolytic condensation of an organotrialkoxysilane and/or its partial hydrolyzate in an alkaline aqueous solution.例文帳に追加

オルガノトリアルコキシシランおよび／またはその部分加水分解物をアルカリ水溶液中で加水分解・縮合させて球状ポリオルガノシルセスキオキサン微粒子を製造するにあたり、変動係数が小さく粒径の揃った微粒子を簡単な反応により効率よく製造する。 - 特許庁

The spherical silsesquioxane fine particle having the average value of the particle size of 10-30 nm and a variation coefficient of particle sizes of 15% or less is produced by bringing a specific silanol-forming silicon compound into contact with a fixed amount of water in the presence of a prescribed amount of a specific acid catalyst and simultaneously carrying out hydrolysis reaction and condensation reaction at a prescribed temperature.例文帳に追加

特定のシラノール形成性ケイ素化合物を、所定量の特定の酸触媒の存在下で、所定量の水と接触させ、所定の温度下で加水分解反応及び縮合反応を同時に行なわせて、粒子径の平均値が１０〜３０ｎｍ且つ粒子径の変動係数が１５％以下の球状シルセスキオキサン微粒子とした。 - 特許庁
