说明

General description

2，2，4-三甲基戊烷（TMP，异辛烷）是饱和的支链烃。据报道对雄性大鼠有肾毒性。研究了TMP在不同温度（198K-348K）和压力（100MPa）下的密度和黏度。它已被确定为无铅汽油中的肾毒性诱导成分。

Application

2，2，4-三甲基戊烷（TMP，异辛烷）可用于评估TMP和环己烷的二元混合物的各种物理性质（密度，黏度，折射率和表面张力）。

2,2,4-Trimethylpentane-induced nephrotoxicity. II. The reversible binding of a TMP metabolite to a renal protein fraction containing alpha 2u-globulin.

E A Lock et al.

Toxicology and applied pharmacology, 91(2), 182-192 (1987-11-01)

Trimethylpentane (TMP) produces nephrotoxicity in male but not in female rats. The toxicity is characterized by an increase in protein droplets in proximal convoluted tubular cells and an increase in the renal concentration of the male-rat-specific protein alpha 2u-globulin. Subcellular
