Abstract

To provide a propellant which has sufficient propelling performance and of which a component to be sprayed imposes low environmental burden, a propellant composition and a sprayer. A propellant composition comprising a propellant containing 1-chloro-2,3,3,3-tetrafluoropropene and a pressurizing agent, and a sprayer comprising the propellant composition, a container in which the propellant composition is contained, and a spray unit to spray the propellant composition to the outside of the container.

First claim

What is claimed is:

1 . A propellant composition comprising a propellant containing 1-chloro-2,3,3,3-tetrafluoropropene and a pressurizing agent.

2 . The propellant composition according to claim 1 , wherein the pressurizing agent is at least one member selected from propane, butane, isobutane, dimethyl ether, a hydrofluoroolefin, a hydrofluorocarbon, carbon dioxide, compressed air, nitrous oxide and nitrogen.

3 . The propellant composition according to claim 1 , which further contains a spray chemical agent.

4 . The propellant composition according to claim 1 , wherein the vapor pressure of the propellant composition at 0° C. is higher than atmospheric pressure.

5 . The propellant composition according to claim 1 , wherein the proportion of 1-chloro-2,3,3,3-tetrafuoropropene to the total amount of the propellant is at least 10 mass % and at most 90 mass %.

6 . The propellant composition according to claim 1 , wherein the 1-chloro-2,3,3,3-tetrafluoropropene consists of (Z)-1-chloro-2,3,3,3-tetrafluoropropene and (E)-1-chloro-2,3,3,3-tetrafluoropropene, and the proportion of (Z)-1-chloro-2,3,3,3-tetrafluoropropene to the total amount of 1-chloro-2,3,3,3-tetrafluoropropene is at least 50 mass % and at most 99.99 mass %.

7 . A sprayer comprising the propellant composition as defined in claim 1 , a container in which the propellant composition is contained, and a spray unit to spray the propellant composition to the outside of the container.

8 . A propellant containing 1-chloro-2,3,3,3-tetrafluoropropene and a pressurizing agent.

9 . The propellant according to claim 8 , wherein the pressurizing agent is at least one member selected from propane, butane, isobutane, dimethyl ether, a hydrofluoroolefin, a hydrofluorocarbon, carbon dioxide, compressed air, nitrous oxide and nitrogen.

10 . The propellant according to claim 8 , wherein the proportion of 1-chloro-2,3,3,3-tetrafuoropropene to the total amount of the propellant is at least 10 mass % and at most 90 mass %.
