IDENTIFICATION AND USE: Triacontane is a higher n-alkane containing 30 carbon atoms (C30). HUMAN EXPOSURE AND TOXICITY: There are no data available. ANIMAL STUDIES: A homologous series of n-alkanes ranging from n-C12-n-C31 was found in all samples of liver, heart, kidneys, muscle and adipose bovine tissues.
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aliphatic hydrocarbons and related compounds/
/SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . Treat frostbite with rapid rewarming techniques ... ./Aliphatic hydrocarbons and related compounds/
/SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Treat seizures with diazepam (Valium) or lorazepam (Ativan) ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Aliphatic hydrocarbons and related compounds/
Emergency and supportive measures. 1. General. Provide basic supportive care for all symptomatic patients. Maintain an open airway and assist ventilation if necessary. Administer supplemental oxygen. Monitor arterial blood gases or oximetry, chest radiographs, and ECG and admit symptomatic patients to an intensive care setting. Use epinephrine and other beta-adrenergic medications with caution in patients with significant hydrocarbon intoxication because arrhythmias may be induced. 2. Pulmonary aspiration. Patients who remain completely asymptomatic after 4-6 hours of observation may be discharged. In contrast, if the patient is coughing on arrival, aspiration probably has occurred. Administer supplemental oxygen and treat bronchospasm and hypoxia if they occur. Do not use steroids or prophylactic antibiotics. 3. Ingestion. In the vast majority of accidental childhood ingestions, less than 5-10 mL is actually swallowed and systemic toxicity is rare. Treatment is primarily supportive. Injection. For injections into the fingertip or hand, especially those involving a high-pressure paint gun, consult with a plastic or hand surgeon immediately, as prompt wide exposure, irrigation, and debridement are often required. /Hydrocarbons/
Liver, heart, kidneys, muscle and adipose (perirenal and s.c.) /bovine/ tissues were collected from 6 animals for analysis of their hydrocarbon composition. Qualitative and quantitative determinations were carried out by gas chromatography and combined gas chromatography-mass spectrometry. Although differing in the proportions, a homologous series of n-alkanes ranging from n-C12-n-C31 was found in all samples. The isoprenoid hydrocarbons phytane and phytene (phyt-1-ene and phyt-2-ene) were also identified. (These findings have relevance to the health of humans consuming hydrocarbon-contaminated meats.) /n-Alkanes/
In the presence of hydroxy-radicals, palmitic, oleic, and linoleic acids are partially transformed into the corresponding C2n–2 hydrocarbon and a Cn–1 alcohol. The double bonds in unsaturated acids may be preserved by performing the reaction in a heterogeneous system.

The present invention is directed to unsaturated or derivatized long chain (C22-C50) polyunsaturated hydrocarbons and a method of preparing the long chain hydrocarbons via electrocoupling of C12-C26 fatty acids. It has been found that soapstock is an inexpensive source of starting materials for the present method. The present invention is also directed to compositions comprising the long chain polyunsaturated hydrocarbons, which can be used as reactive diluents and modifiers in latex, epoxy, alkyd and polymer compositions. In another aspect, the present invention is directed to derivitization or ozonolysis of the long chain polyunsaturated hydrocarbons. The present method is also useful for preparing C12-26 alkyl esters and C12-26 carbon chain compounds containing a terminal olefin.

A fully heterogeneous and highly efficient dual catalyst system for alkane metathesis (AM) has been developed. The system is comprised of an alumina‐supported iridiumpincercatalyst for alkanedehydrogenation/olefin hydrogenation and a second heterogeneous olefin metathesis catalyst. The iridiumcatalysts bear basic functional groups on the aromatic backbone of the pincer ligand and are strongly adsorbed

Esters (mixed anhydrides) derived from aliphatic or alicyclic carboxylic acids (RCO2H) and thiohydroxamic acids or undergo a thermally or photochemically induced radical chain reaction to give sulphides with loss of carbon dioxide. On irradiation at low-temperature however, the chain reaction is essentially supressed. Under these conditions moderate to good yields of dimers R-R are obtained from primary
