    • A carbonylation catalytic system comprises (A) a combination of (A1) a Group VIII metal source of Periodic Table of the Elements (e.g., palladium, palladium chloride) supported on a carrier, (A2) a ligand such as triphenylphosphine and (A3) an acid such as an alkyl-sulfonic acid, or (B) a combination of (B1) the Group VIII metal source except for palladium (e.g., a platinum compound), (B2) a ligand such as triphenylphosphine and (B3) an electron donative compound having an electron donability .DELTA..nu.D of not less than 2 (for instance, an amine such as a heterocyclic tertiary amine). The catalytic system (B) may further comprise (B4) an acid such as methanesulfonic acid. In the presence of the catalytic system (A) or (B), an acetylenic or olefinic unsaturated compound is allowed to react with carbon monoxide and a nucleophilic compound having an active hydrogen such as water, an alcohol and a carboxylic acid in a liquid phase to give an unsaturated or saturated carboxylic acid or an ester thereof with high transformation rate and selectivity.
    • 羰基化催化体系包括(A)负载在载体上的(A1)元素周期表第Ⅷ族金属源(例如钯,氯化钯),(A2)配体如三苯基膦和(A3) 一种酸如烷基磺酸,或(B)除了钯(例如铂化合物)之外的(B1)第Ⅷ族金属源,(B2)配体如三苯基膦和(B3)电子的组合 具有不小于2的电子偶联性DELTA nu D的助孕化合物(例如,胺如杂环叔胺)。 催化体系(B)还可以包含(B4)酸,例如甲磺酸。 在催化体系(A)或(B)的存在下,允许炔属或烯属不饱和化合物与一氧化碳和具有活性氢的亲核化合物如水,醇和羧酸在液相中反应 得到具有高转化率和选择性的不饱和或饱和羧酸或其酯。

    • A granulated product of potassium sorbate (i) has an overall pore volume of 0.3 ml/g or less, (ii) has an Na content of 450 ppm or less, or (iii) has an overall pore volume of 0.4 ml/g or less, or a granule hardness of 15% or less, and an Na content of 1000 ppm or less. The granulated product is obtained, for example, (i) by granulating a potassium sorbate aqueous solution through fluidized bed granulation drying, (ii) by neutralizing sorbic acid with a potassium sorbate having a molar ratio of Na to K (Na/K) of 0.0024 or less to yield potassium sorbate, and granulating the potassium sorbate, or (iii) by neutralizing sorbic acid with a potassium sorbate having a molar ratio of Na to K (Na/K) of 0.006 or less to yield potassium sorbate, and moisture-conditioning 100 parts by weight of the potassium sorbate with 1 to 8.5 parts by weight of water and 1 to 8 parts by weight of a water-soluble organic solvent and subjecting the resulting mixture to extrusion granulation. The granulated product of potassium sorbate has a highly stable hue over time.
    • 山梨酸钾(i)的造粒产物的总孔体积为0.3ml / g以下,(ii)Na含量为450ppm以下,或(iii)总孔体积为0.4ml / g,或 或者颗粒硬度为15%以下,Na含量为1000ppm以下。 得到造粒物,例如,(i)通过流化床造粒干燥将山梨酸钾水溶液制粒,(ii)通过用山梨酸钾与Na摩尔比K(Na / K)的山梨酸钾中和山梨酸 0.0024以下,得到山梨酸钾,并使山梨酸钾成粒,或者(iii)通过用摩尔比为Na〜K(Na / K)为0.006以下的山梨酸钾中和山梨酸,得到山梨酸钾, 用1〜8.5重量份的水和1〜8重量份的水溶性有机溶剂调节100重量份的山梨酸钾,并将所得混合物进行挤出造粒。 山梨酸钾的粒状产品随着时间的推移具有高度稳定的色调。
