用途：

用于有机合成。

异辛酸亚锡是白色或淡黄棕色膏状物，有时称作辛酸亚锡。溶于石油醚，不溶于水。是生产聚氨酯泡沫塑料的基本催化剂，主要用于聚醚－聚氨酯发泡时的胶化反应，也可以作为氨酯泡沫塑料防老剂。用作聚氨酯合成和室温硫化硅橡胶的催化剂。也用作环氧树脂催化剂型固化剂，在固化时辛酸亚锡比二月桂酸二丁基锡催化活性大，若将二者复配使用，其效果比单独使用好，可兼顾反应速度和固化速度。由于二价锡化合物易被空气中氧和水汽氧化与分解，因此储存时要用于氮保护，***密封，避免高温和过大湿度，以防活性下降或失效。

储运：

应密封保存，储存于干燥阴凉通风仓库内

包装：

200KG/桶 贮存：建议存储在干燥和凉爽的地区并进行适当通风。原包装后请尽快扣紧包装盖，以防水分等其他物质的混入而影响产品性能。储存在阴凉、干燥的地方，保持容器密封，避免与氧化物接触。不要吸入粉尘， 避免皮肤和黏膜接触。工作场所禁止吸烟、进食和饮水。工作后，淋浴更衣。单独存放被污染的衣服，洗后再用。保持良好的卫生习惯。

USES:

Used in organic synthesis.

Stannous isocaprylate is a white or yellowish-brown paste, sometimes called stannous caprylate. Soluble in petroleum , insoluble in water. It is the basic catalyst for the production of polyurethane foams, mainly used in the gelatinization reaction of polyether-polyurethane foams, and can also be used as the aging agent of polyurethane foams. Used as catalyst for polyurethane synthesis and room temperature vulcanized silicone rubber. It is also used as curing agent for epoxy resin catalysis. During curing, tin octanoic acid has higher catalytic activity than dibutyltin dilaurate. If the two are combined, the effect is better than that of single use, and both reaction speed and curing speed can be taken into account. Because divalent tin compounds are easily oxidized and decomposed by oxygen and water vapor in the air, storage for nitrogen protection must be sealed to avoid high temperature and excessive humidity to prevent degradation or failure of activity.

Storage and transportation:
