A composition including the compound HFO-1234yf and at least one other, additional, compound selected from HCFC-240db, HCFO-1233xf, HCFC-243db, HCFO-1233zd, HCC-40, HCFC-114a, HCFC-115, HCFC-122, HCFC-23, HCFC-124, HCFC-124a, HFC-125, HCFC-133a, HCFC-142, HCFC-143, HFC-52a, HCFC-243ab, HCFC-244eb, HFC-281ea, HCO-1110, HCFO-1111, HCFO-1113, HCFO-1223xd, and HCFO-1224xe. A composition including the compound HFO-1234yf and at least two compounds selected from HFO-1234ze, HFC-245cb, HFC-134a, HCFC-115, HFC-152a, HCC-40 and HFO-1243zf. 1. A composition comprising the compound HFO-1234yf and at least one other additional compound chosen from HCFC-240db, HCFO-1233xf, HCFC-243db, HCFO-1233zd, HCC-40, HCFC-114a, HCFC-115, HCFC-122, HCFC-123, HCFC-124, HCFC-124a, HFC-125, HCFC-133a, HCFC-142, HCFC-143, HFC-152a, HCFC-243ab, HCFC-244eb, HFC-281ea, HCO-1110, HCFO-1111, HCFO-1113, HCFO-1223xd and HCFO-1224xe. The present application is a continuation of U.S. application Ser. No. 14/651,855, filed on Jun. 12, 2015, which is a U.S. national phase application of International Application No. PCT/FR2013/052977, filed on Dec. 6, 2013, claims the benefit of French Application No. 12.62766, filed on Dec. 26, 2012. The entire contents of each of U.S. application Ser. No. 14/651,855, International Application No. PCT/FR2013/052977, French Application No. 12.62766, are hereby incorporated herein by reference in their entirety.The present invention relates to compositions comprising 2,3,3,3-tetrafluoropropene, which are of use in many fields of application such as refrigeration, blowing agents, solvents and aerosols.One very important parameter in the choice of a composition of use in the fields of refrigeration, air conditioning and heat pumps is its impact on the environment. The manufacture of 2,3,3,3-tetrafluoropropene (HFO-1234yf), being accompanied by a multitude of by-products having a boiling point close to HFO-1234yf, results in quite complex and expensive purification steps.
