Abstract
Diethylene glycol monoterpenyl ethers (containing terpenyl group : isobornyl [11], n-bornyl [16], 1-β-fenchyl [18], α-terpinyl [23] and β-terpinyl [28]), triethylene glycol monoterpenyl ethers (containing terpenyl group : isobornyl [12], n-bornyl [17] 1-β-fenchyl [19] and α-terpinyl [24]) and polyethylene glycol monoterpenyl ethers (containing terpenyl group : isobornyl [13], [14], [15], 1-β- fenchyl [20], [21], [22] and α-terpinyl [25], [26], [27]) were prepared by the reaction of various terpene hydrocarbons such ascamphene [1], tricyclene [2], 2-pinene [3], 2 (10) -pinene [4] and 1, 8-p-menthadiene [5] with diethylene glycol [6], triethylene glycol [7] and polyethylene glycol (MW=200 [8], 400 [9], 600 [10]) in the presence of cation exchange resin at 50°+2°C. These structures were confirmed by physical constants, IR and NMR. Surface activities such as surface tention, foaming property, penetrating power solubilizing power and emulsifying power of these nonionic surfactants were investigated.
As a result, triethylene glycol monoisobornyl ether [12], di-and triethylene glycol mono-α-terpinyl ether [23] and [24] had far better penetrating power than LAS (sodium linear alkyl benzene sulfonate). Polyethylene glycol monoisobornyl ether [13] [15] and polyethylene glycol mono-α-terpinyl ether [25] [27] had far lower foaming property than LAS. And also, [14], [26] had far better penetrating power and solubilizing power than LAS.
