Description

Detergency SDL15B
Product introduction
Detergency SDL15B is one of the series of lubricant additives developed by us through technical cooperation with Sinopec Research Institute of Petroleum Processing. It’s made from dodecylphenol by means of vulcanization, neutralization and high-base reaction. This product is a kind of widely used lubricant additive of comprehensive performance, boasts extremely good acid neutralization capacity and high-temperature detergency, excellent oxidation resistance and corrosion control as well as good emulsion resistance and oil solubility. It’s compatible with sulphonates, alkenyl succinimide, ZDDP and other additives. It has prominent effect in reducing top-piston ring carbon and is widely used to prepare middle and high-grade ICE oils.

  1. High-temperature detergency
By coke board simulation test, the high-temperature detergencies of several sulfurized calcium alkyl phenolates with high base numbers are compared.

Phenoxide Base Number, mgKOH/g Increased Coke Board Wt, mg
SDL15B 256 30.6
Reference 1, overseas 241 31.0
Reference 2, China 255 42.0
Reference 3, China 256 50.9
Notes: 1)The samples with phenoxide density 1.6% contain 15W/40 multi-level base oils, are prepared with 150SN, 500SN and 150BS base oils and viscosity index improvers, anti-foam additive and so on.
2)Test condition: Oil temp. 100℃, board temp. 320℃, oil splash 15S, time interval 45S, and time 2h.
3.3 Acid neutralization capacity
Table 4 The acid neutralization capacities of several sulfurized calcium alkyl phenolates with high base numbers

SDL15B 1050 18.7 0.0163 0.3385
Reference 1, overseas 1200 23.4 0.0195 0.4620
Reference 3, China 1200 13.7 0.014 0.2078
Note:
For the base oils with base number 5mgKOH/g: 150SN.
Test indicates that SDL15B enjoys quicker neutralizing speed and moderate CO2 release per base number.
