Embodiment 1

[0015] Add 70 g of α-pinene, 30 g of isopropanol, and 0.1 g of tetraethylammonium bromide catalyst into a 500 mL autoclave, stir and heat up to 120°C. Add carbon dioxide from the guide pipe to make the pressure of the reactor reach 4MPa, and start stirring. During the reaction process, the carbon dioxide pressure was controlled between 4MPa±0.02MPa, and the reaction time was 6 hours. Then reduce the temperature of the reactor to 40°C, and vent excess carbon dioxide through the guide tube. The material was discharged from the bottom of the reaction kettle to obtain light yellow transparent liquid A-terpene isopropyl carbonate.

Embodiment 2

[0017] Add 84 g of α-pinene, 30 g of isopropanol, and 0.2 g of tetraethylammonium bromide catalyst into a 500 mL autoclave, and stir to raise the temperature to 80°C. Add carbon dioxide from the guide tube to make the pressure of the reactor reach 6MPa, and start stirring. During the reaction process, the carbon dioxide pressure was controlled between 6MPa±0.02MPa, and the reaction time was 6 hours. Then reduce the temperature of the reactor to 40°C, and vent excess carbon dioxide through the guide tube. The material was released from the bottom of the reaction kettle to obtain light yellow transparent liquid B-terpene isopropyl carbonate.

Embodiment 3

[0019] Add 70 g of α-pinene, 30 g of isopropanol, and 0.5 g of tetraethylammonium bromide catalyst into a 500 mL autoclave, stir and heat up to 60°C. Add carbon dioxide from the guide pipe to make the pressure of the reactor reach 8MPa, and start stirring. During the reaction process, the carbon dioxide pressure was controlled between 8MPa±0.02MPa, and the reaction time was 6 hours. Then reduce the temperature of the reactor to 40°C, and vent excess carbon dioxide through the guide tube. The material was released from the bottom of the reaction kettle to obtain light yellow transparent liquid C-terpene isopropyl carbonate.

Abstract

The invention relates to the technical field of antiknock, and specifically relates to a terpene isopropyl carbonate gasoline antiknock. The gasoline antiknock of the invention has unique performance and purpose, and can be used as a novel functional compound. A octane number of gasoline can be raised with a small amount of the antiknock, so as to raise gasoline explosion-proof effect. The gasoline antiknock of the invention comprises raw materials of, by weight, 0.1-3.0 parts of tetraethylammonium bromide, 60-100 parts of alpha-pinene and 20-40 parts of isopropanol.

Description

1. Technical field: [0001] The invention relates to the technical field of antiknock agents, in particular to a terpene isopropyl carbonate gasoline antiknock agent. 2. Background technology: [0002] Gasoline is the main power fuel for automobile engines. With the development of automobiles and technological progress, the requirements for gasoline are getting higher and higher. Improving the quality of gasoline is an inevitable trend. Adding gasoline antiknock agents is one of the methods to increase the octane number of gasoline , gasoline antiknock agent is a class of chemical substances that can improve gasoline combustion and increase the octane number of gasoline, and the octane number of gasoline is one of the keys to reflect the quality of gasoline. For gasoline, only a small amount of The antiknock agent can effectively increase the octane number of gasoline, which is a simple and effective way for refineries to increase gasoline production, save energy, improve pro...
