毒理性
四氟甲烷(CF4)是一种无色无味的气体。它被用作低温制冷剂;气体绝缘体。它还用于半导体工业中硅晶圆的等离子体刻蚀。人类接触和毒性:通过吸入可能导致混淆、头痛。动物研究:四氟甲烷导致豚鼠回肠乙酰胆碱分泌增加。研究了气体 -Ar和 -SF6的二元混合物的麻醉效力,实验对象为小鼠。
IDENTIFICATION AND USE: Tetrafluoromethane (CF4) is a colorless odorless gas. It is used as low temperature refrigerant; gaseous insulator. It is also used for plasma etching of silicon wafers in the semiconductor industry. HUMAN EXPOSURE AND TOXICITY: It can cause confusion, headache by inhalation. ANIMAL STUDIES: Tetrafluoromethane caused increases in acetylcholine output from the guinea-pig ileum. The anesthetic potencies of binary mixtures of the gases CF4-Ar and CF4-SF6 were studied in mice.
