Hazard Classes and CategoriesFlam. Liq. 2 (100%)；Asp. Tox. 1 (100%)；Skin Irrit. 2 (89.1%)；Eye Irrit. 2 (89.1%)；STOT SE 3 (82.6%)

毒性情報

TreatmentTreatment is mainly symptomatic and supportive. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. (A600)

Health EffectsPetroleum distillates are aspiration hazards and may cause pulmonary damage, central nervous system depression, and cardiac effects such as cardiac arrhythmias. They may also affect the blood, immune system, liver, and kidney. (A600, L1297)

Exposure RoutesOral (L400) ; inhalation (L400) ; dermal (L400)

Toxicity SummaryPetroleum distillates are central nervous system depressants and cause pulmonary damage. (A600)

Signs and Symptoms · 1 件

Petroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia. At high amounts, central nervous system depression may also occur, with symptoms such as weakness, dizziness, slow and shallow respiration, unconsciousness, and convulsions. Petroleum distillates are also irritating to the skin. (A594)

Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).

化学と産業

薬理情報

Metabolism/MetabolitesVolatile hydrocarbons are absorbed mainly through the lungs, and may also enter the body after ingestion via aspiration. (A600)

用途と製造

UsesPentenes are components of gasoline and are often produced as by-products of catalytic of thermal cracking of petroleum. (L1287)

General Manufacturing Information2-Pentene: ACTIVE

応用分野

使用2-Pentene (mixture of cis and trans) is used in the synthesis of polycyclopentene by ring-opening metathesis polymerization.

一般的な説明2-Pentene undergoes addition reaction with phenoxathiin cation radical in acetonitrile solution to form bis(10-phenoxathiiniumyl)alkane adducts.

調製方法

純化方法Reflux the mixture with sodium wire, then fractionally distil it twice through a Fenske (glass helices packing, p 11) column. [Beilstein 1 IV 815.]
